CLOSING RECEPTION
Indian Wells NOP
It was a great pleasure for us to hold our 25 th
Anniversary meeting last year in beautiful Portland, Oregon. Looking back on the 1970s and 1980s, CS (compound semiconductors) produced lots of dreams, innovations, and new generations of engineers and scientists, but did not hit financially successful products in the field of microwave devices. After losing the battle with Si in the development and commercialization of the high speed CPU, a savior came in the form of a small handheld device: the cellular phone. This device needed exotic materials and speed that
Si could not match and it came in the form of GaAs devices using HBTs and pHEMTs for wireless communication. After focusing on manufacturing and commercialization, we finally have grown to become an important industry in RF applications. We have continued with our growth after the 20 th
century in spite of facing a financial crisis. We continuously look at new materials and recently GaN and SiC have been showing great potential for RF applications. We still have many challenges ahead as we incorporate new materials into the manufacturing environment, but this has not stopped us from innovating. As we start a new year, we are reminded that we are entering a new era of “wireless everywhere” with new generations of smartphones, eBooks, smart grid, etc…. CS will surely play an important role in these applications as well as for LEDs, lighting, and solar cells.
The CS MANTECH Conference is the best place to check out what is important and new in the CS community.
This year we gather in Palms Springs, California, one of the most beautiful places in Southern California with warm temperatures year around. Palm Springs offers beautiful
4 2011 Compound Semiconductor MANTECH
landscapes, fine dining, shopping, or simply relaxation.
And if you are into more active pursuits, Palm Springs has some of the best golf courses in the world.
The purpose of CS MANTECH is very clear. We strive to contribute to the overall CS industry from manufacturing to market information. We help provide a venue where ideas can be exchanged freely with expanded communication among participants from academia, industry, and government. I am very excited that you can join our family, and I welcome any ideas that would help enrich our experience.
There will be a broad array of educational opportunities including our Monday workshops. From the last conference in 2010, the ROCS (Reliability of Compound
Semiconductors) Workshop started co-locating with CS
MANTECH. You can choose the MANTECH workshop and/or ROCS on Monday.
Students can also interact with potential employers.
Industry veterans can keep contact with old friends, meet new ones, and take the pulse of the industry. The technical sessions will offer the current state of the art in materials, processing, reliability, and device technology across the compound semiconductor spectrum.
This is the annual event where our industry comes together. Come join us!

6 2011 Compound Semiconductor MANTECH
The 2011 CS MANTECH program begins on Monday
May 16 th
with a series of tutorial workshops. This year’s workshops will focus on device/process simulation, modeling, high frequency measurement and characterization, passive and EM simulation and design kit infrastructures. The workshop theme is “From Process to
Product”. In addition, this year CS MANTECH will host the internationally acclaimed ROCS Workshop (Reliability of Compound Semiconductors) which will be held on the opening day (Mon 5/16). The ROCS Workshop will present the latest results and new developments in all phases of Compound Semiconductor Reliability (see http://www.jedec.org/home/gaas/ for details).
On Monday evening the Exhibits open at 6:00 pm with the traditional Exhibits Reception. The CS MANTECH exhibits are an excellent opportunity to view suppliers of materials, services and tools from around the globe. This is a great time to renew old relationships and establish new ones while enjoying the fine food and libations of Indian
Wells (Palm Springs).
The CS MANTECH Conference formally opens on
Tuesday morning with a brief overview of the conference and the awards presentation for the best papers from the
2010 conference. This is immediately followed by the two
Plenary Sessions which will cover topics ranging from the latest in RF module technology to the newest in high frequency devices.
After lunch, we’ll see an analysis of our business and technology trends, followed by a session covering 3G/4G and LTE requirements for wireless systems and the role compound semiconductor devices play in meeting these requirements.
The Tuesday technical session will conclude with our
Exhibitor’s Forum. Also, in parallel will be our Student
Forum, which is designed to be an interactive session between students and the industry that is destined to hire them. As Tuesday evening approaches, we will walk out of the Hyatt Grand Champions to Indian Wells Golf Resort where we’ll eat, drink, and enjoy a 9-hole putting contest with old and new friends.
The Sessions on Wednesday morning will start with two parallel invited talks describing the Future of Compound
Semiconductor Technologies in India and in China. Then we start the parallel sessions with world class technical papers on the compound semiconductor industry. One side of Wednesday’s two parallel sessions focuses on emerging
7 2011 Compound Semiconductor MANTECH
wide band-gap technologies, and the other on manufacturing practices and processing. These are topics for which CS MANTECH is well known.
In order to allow additional opportunity to interact with the
Exhibitors before the Exhibits close, this year we will have a longer one hour break during the morning session to take place in the exhibit hall.
Wednesday evening features the popular Rump Sessions.
Eat, drink, and debate! Attendees may join any or all (if you move quickly) of the four parallel topics, where moderators will encourage informal, lively, and highly interactive discussions.
The Sessions on Thursday morning will start a little later and the day will proceed with parallel sessions. The morning continues with excellent technical papers on
Emerging Technologies, LEDs, simulation & characterization, and reliability. Following this session lunch will be sponsored by CS MANTECH. Thursday afternoon will include our closing two sessions on fab management/technology transfer and power switches followed by the Interactive Forum poster session. This poster session includes new papers on a diverse range of topics, as well as poster versions of all the papers presented earlier in the technical program. Attendees will have the opportunity to meet with authors to discuss their papers in detail. Attendees of the Interactive Forum will vote for the best poster, and the winning author will receive the
Best Poster Award.
The Conference Closing Reception will follow the
Interactive Forum. In a warped and hopefully humorous manner we will be holding a Haiku contest with CS
MANTECH as the theme for the writings. In English,
Haiku most often takes the form of three lines with a 5, then 7, then 5 syllable format. Limit of one submission per person, please. Our closing reception will also feature a drawing for an iPod. All those who completed and submitted their Feedback Forms will have a chance to win!
8 2011 Compound Semiconductor MANTECH
Traditionally CS MANTECH offers Monday workshops featuring topics of interest to the compound semiconductor community. Workshop attendees get the opportunity to expand their knowledge beyond their own specialties, as industry experts share their knowledge and valuable experiences in a tutorial manner. Past programs have offered many interesting topics ranging from materials and processing, test and characterization, applications and market analysis, to engineering management and intellectual property rights. This year’s Workshop theme is “ From Process to Product ”. CS MANTECH is pleased to offer a series of talks to cover device/process simulation, modeling, high frequency measurements and characterization, passive and EM simulation and design kit infrastructures. These invited talks are intended to provide the Workshop attendees with an opportunity to appreciate what product/circuit designers care about at the circuit level and how processing information is used in the realization of products by other groups. This allows process development and sustaining teams to have a better understanding of how product and circuit level needs translate to process technology requirements. The planned tutorials deliver a good overview for those just wanting to learn more, but will also provide sufficient breadth of topics and detail that even those in the field will learn something new.
Our workshops will begin with a talk by Dr. Charlie Fields from HRL Laboratories, LLC. His presentation covers the use of process simulation tools to assist the development of compound semiconductor devices and circuits. He will discuss the capability of qualitative and quantitative analysis of device and circuit cross-sections to uncover potential device/circuit failures and reliability issues by simulation tools. He will share simulation results that allow verification of process design rules with the goal of design for manufacturability.
His talk highlights the benefits of using process simulation tools to design a fabrication process that is robust and high yield in the process development stage.
As we know, a robust and high yield process reduces the expense of IC failure analysis as well as the overall product cost.
Dr. Fields has a Ph.D. from the University of California at Berkeley and is a
Senior Project Manager and the Trusted Foundry Program
Manager at HRL. His current research work involves photolithography for advanced III-V devices and circuits, process simulation, and high frequency device characterization and modeling.
9 2011 Compound Semiconductor MANTECH
The second talk will be presented by Dr. Pete Zampardi from Skyworks Solutions, Inc. His talk will focus on
“Modeling for Process”. This tutorial discusses the overall strategy for developing and implementing simple physicsbased models, including statistics, for the design of RF circuits in GaAs HBT or BiFET technology. While the examples used target the development of handset power amplifiers, the general principle is applicable to other devices and technologies (the analogies for some other technologies will be discussed). Key features of this approach are: the idea of “unified” models where devices share parameters if they are constructed from the same physical process layers, the use of Design-of-Experiments
(DOE) to define the variations and minimize the required number of simulation runs, and the idea of a “device-up” approach that uses basic device physics and process information to define the factors and determine model parameter correlation using experimental DOE. Using this approach, the links between process parameters, model parameters, and circuit performance become much clearer than using curve-fitting. This approach can also be used to enhance already existing models with a few simple modifications. Specific examples of GaAs HBTs and
GaAs MESFETs from a BiFET process will be presented.
Dr. Zampardi has a Ph.D. from the University of California at Los Angeles and currently is a Technical Director for
Device Design, Modeling, and Characterization at
Skyworks.
The next talk is an Electronic Design Automation (EDA) tutorial focused on FET and pHEMT Modeling and
Characterization. Mr. Paul Litzenberg of TriQuint
Semiconductor will briefly explore pHEMT small signal and noise models, and then focus primarily on large signal
(nonlinear) pHEMT models. Different bias regions of pHEMT operation and the “compact” model equation sets commonly used to model behavior in these respective regions will be described. The process of pHEMT characterization, model parameter extraction, and model verification will be presented. The accuracy of several large signal models, including Angelov, EEHEMT and
TOM4, will be illustrated through comparison of simulated and measured device characteristics. Finally, advanced pHEMT modeling topics will be discussed including temperature variation, process (manufacturing) variation, and size scaling. Mr. Litzenberg is the Commercial
Foundry Engineering Director at TriQuint Semiconductor in Hillsboro Oregon. He leads a team of engineers and technicians who develop and maintain the Process
Development Kits (PDK’s) for all TriQuint 150 mm GaAs
IC process technologies, FET and HBT technologies, including device characterization, model development, model parameter extraction, model verification, layout
10 2011 Compound Semiconductor MANTECH
macros and layout verification. Mr. Litzenberg earned an
MSEE degree from Arizona State University and a BSEE degree from the University of Illinois.
Dr. Marcel Tutt from Freescale will give a tutorial on “RF and Low Noise Measurements for III-V Devices”. III-V
Devices have applications in frequencies ranging from RF to millimeter wave. These applications include low noise amplifiers, power amplifiers, frequency conversion devices, and sources. In order to determine the suitability of a device for a given application or the performance of a
III-V circuit, specialized measurement techniques are required. Dr. Tutt’s talk will explain the key measurement techniques used, including S-parameters, load pull, and noise parameter determination. Measurement theory, principles, and interpretation will be covered. Dr. Tutt received his Ph.D. from the University of Michigan. His research dealt with noise properties of HEMT’s and GaAs
HBT’s. He has worked in the areas of microwaves and millimeter waves (mmW) for over 20 years. When he joined Freescale he developed the modeling process for their III-V HBT’s for handset PA applications. Later, he managed Freescale’s III-V device modeling and characterization group and has supervised the development of on-wafer mmW test systems for the characterization of mmW devices and circuits at Freescale.
The fifth talk by Mr. Michael Thompson of Agilent
Technologies will share the methods and practical examples of passive and EM simulations. From High
Speed Digital applications to RF and microwave frequency boards, modules, and ICs these simulation techniques are a cornerstone in the design of current electrical systems.
But, in spite of advances in analysis techniques and the development of faster and more capable computer systems, the designer still cannot analyze every physical detail of a design and must make judgments about what areas of the design to analyze, and in how much detail. Mr.
Thompson’s talk reviews the more popular analysis method, but focuses mainly on the trade-offs required by the designer to model critical portions of the design while still meeting design and development time lines. Mr.
Thompson received a BSEE and a ME, Microwave
Engineering Option, from Cal Poly, Pomona, in 1982 and
1986 respectively, followed by post graduate work in
Electro Magnetics and Antenna Theory at USC.
He joined
HP in 1997 and has remained within the EEsof Division throughout the spin-off from HP to Agilent where he was an Application Engineer (AE) from 1997 to 2008 and is currently the Western US AE District Manger.
Last but not least, our final talk will be presented by Dr.
Hongxiao Shao from Skyworks Solutions, Inc. Dr. Shao
11 2011 Compound Semiconductor MANTECH
will explore the objectives and methods of developing and implementing Electronic Design Automation (EDA) and process design kits (PDK) infrastructure with special considerations for a high volume manufacturing environment. His presentation will demonstrate one of the few PDKs for compound semiconductor process technologies with a complete implementation of electrical / physical / electricomagnetic and statistical yield / manufacturability functionalities, emphasizing large signal
RF MMIC applications. The underlying EDA solutions and automation opportunities between design, manufacturing, and industrial engineering will also be discussed. The problems a PDK addresses will be elaborated for two somewhat opposite aspects of a semiconductor process. One end of the spectrum is the application – focusing on the total cost of product development, especially the pains experienced by designers, while the other is the process development – focusing on the application support and releases, especially the migration of a product from one generation technology to the next. Clear distinctions will be made for PDK implementation considerations for mature technologies, and ones in development, for applications of technology to initial and derivative product development. Dr. Hongxiao
Shao received his Ph.D. in Computational Condensed
Matter Physics from Rutgers University, and currently he is a Senior Engineering Manager in charge of Design Kit and Design Environment development for
Semiconductor/Package Process Technologies at
Skyworks.

In a warped and hopefully humorous manner we will be holding a Haiku contest with CS MANTECH as the theme for the writings. In English, a Haiku most often takes the form of three lines with 5, then 7, then 5 syllable format.
Here is a wonderful example from our TPC member Jim
Crites:
As spring always comes
Technology must advance
MANTECH can assist
Write your CS MANTECH Haiku (limit of one submission per person), print it along with your contact information and pin it to our Haiku board. Attendees will cast the second vote of the day and the winner of the Haiku contest will surely welcome an E-Book reader.
The Conference Closing Reception will bring to an end the 2011 edition of CS MANTECH. It will immediately follow the Interactive Forum. Drinks and snacks will be provided to foster a congenial final opportunity to exchange business cards, ideas, and experiences.
Returning this year is a Feedback Form Raffle. Your opinion on the Feedback Form is very valuable to the CS
MANTECH committees in structuring the conference and programs year-to-year and in choosing the best paper awards. This year, when you turn in your Feedback Form you enter a raffle for an iPod Touch. It’s as simple as that.
The drawing will be held at the Conference Closing
Reception, though you need not be present to win. In addition, votes will be tallied and the Best Poster presentation and best Haiku award winners will be announced.

6:00 PM RUMP SESSIONS
Allen Hanson, M/A-COM Tech Solutions
These popular and often lively sessions offer a venue to voice your opinions and hear your colleagues call it like they see it in a less-formal and often entertaining way.
This year’s line-up of sessions is sure not to disappoint. In
Session A “Which Switch Technology Will Prevail?” attendees polish off their crystal balls and discuss the relative merits of existing and emerging RF switch technologies. In Session B - whether you are a technologist in fear of being out-sourced or a member of an organization touting your foundry services - “The Captive
Compound Semiconductor Fab – Endangered Species?” will surely be of interest and provide participants with an opportunity to weigh-in and share their thoughts, success stories, challenges and perhaps even identify a potential client or two. In Session C - while some critics have branded GaN a technology forever in search of an application, others see it as a true “game changer”. In
“Are There Real High Volume Applications for GaN?” opposing views square-off to debate the future of this emerging technology beyond mere figures of merit. And in Session D “Where Should CS MANTECH Be
Heading?” attendees will be offered a forum to discuss and perhaps shape the future of this conference – its focus, its structure and yes - even your preferred locations. Sure to beat filling out yet another questionnaire!

SESSION 1: PLENARY I - RF SWITCHES
Chair: Mariam Sadaka, Soitec USA
We live in an increasingly wireless world, filled with an ever expanding variety of smart phones, W-LANs,
WWANs, GPS, and a host of other wireless appliances.
Applications of RF technologies continue spreading into new systems like smart grids and e-books and even into entertainment systems and toys. At the core of these wireless systems are RF modules which are powered and enabled primarily by semiconductor devices. Front end module specifications have been made more complex with ongoing evolution of new Cellular standards and band frequencies. Multi-Mode and Multi-Band operation of PA modules is becoming a reality.
Switching and tunable output matching networks can play a pivotal role in this area. Performance requirements such as low insertion loss and high isolation, power handling, and linearity have historically motivated the selection of
GaAs. But recently, Silicon-on-sapphire (SOS) and high resistivity Silicon-on-Insulator (SOI) technologies have also been evaluated for RF switch applications.
This year’s plenary session addresses both Compound
Semiconductor and CMOS-based RF switches. Our first paper by Mitsuhiro Nakamura from Sony describes the integration of E-Mode P-Channel JFETs into their GaAs
E/D-Mode JPHEMT technology for multi-band/mode antenna switch applications. This technology enables fabrication of low power consumption GaAs logic circuits and low loss antenna switches on a single chip. Next paper by Dylan Kelly from Peregrine discusses the golden age of mobile wireless driven by the explosive growth of mobile wireless data traffic. He explains how UltraCMOS on
Silicon-on-sapphire (SOS) technology is addressing the challenges. The session concludes with Randy Wolf of
IBM describing a highly resistive substrate CMOS on SOI technology for wireless front-end applications, which shows a comparable performance to GaAs pHEMT and to
SOS technologies.

SESSION 2: PLENARY II - RF MODULES
Chair: Yohei Otoki, Hitachi Cable America
One of the strongest features of CS-devices is having high performance at GHz frequencies. This has greatly contributed to realizing the wireless mass information transfer era. This Session introduces the latest state of art devices with high frequency from GHz up to THz! First of all, Prof. Jesús A. del Alamo from MIT reviews the history and present topics on HEMTs (High Electron Mobility
Transistors), which is a historical invention of CS devices used to achieve new wireless systems with high frequency performance like satellite broadcast, cellular phones, etc.
30 years have passed after the first HEMT, and you will learn how it has progressed.
Then, development of very high frequency, over 1 THz, electronics - sub-millimeter wave devices - is presented by
John D. Albrecht of DARPA. These devices have incredibly high data resolution, leading to ultra-fine image sensors, radars, and higher speed communication in the near future. You will see the new “image” world. These devices generally use GaAs-,and InP-related materials, but innovations with wide bandgap materials like GaN have come up recently and are showing up in “fast and tough” devices. These devices have been used for the high power amplifiers, but now they are getting into new fields of switching and Low noise application. Raymond Pengelly of Cree, one of the leading companies for GaN devices, presents recent results of development. You will see an
“all GaN module” of Switch and LNA, used at GHz frequencies with very high power in commercial use.
SESSION 3: PLENARY III - BUSINESS ANALYSIS
Chair: Alex Smith, Brewer Science, Inc.
Do you know anyone that does not have some type of mobile device? We are in an amazing industry with products that are changing the world. This session includes three excellent speakers to address a variety of topics of the Compound Semiconductor industry. Eric
Higham of Strategic Analytics will provide an overview of the GaAs Industry from 2009-2014. His paper discusses the history, future drivers, market share leaders, and the competitive threats to GaAs. A question that many in the industry are asking is whether GaN on Silicon will displace
Silicon and SiC in power electronics. Dr. Philippe Rousel from Yole Development will provide his company’s insight on this question and talk about the GaN market in the next four years. The final talk in the session by Quinn
Bolton of Needham & Company, will give a run down on front-end TAM analysis and forecast for the mobile RF devices as driven by the demand for data services.
38 2011 Compound Semiconductor MANTECH
SESSION4: PLENARY IV - CS TECHNOLOGY’S
ROLE IN 4G TERMINALS
Chair: Earl Lum, EJL Wireless Research LLC
While smartphones such as the Apple iPhone and
Motorola’s DROID are changing mobile social behavior, they have been successful due to the reliance on mobile broadband data connections via 3G technologies such as
WCDMA/HSPA and EVDO Rev. A in providing access to the Internet. 3G technologies today can offer downlink data rates up to 42Mbps. Next generation 4G LTE technology promises downlink data rates up to 100Mbps and beyond.
Compound semiconductors such as GaAs have played a pivotal role in the transmit and receive functions of mobile data modem devices as well as mobile phones. Two of the invited papers in this session (from TriQuint
Semiconductor and Qualcomm) focus specifically on the component requirements of 4G LTE terminals including the power amplifier, the LNA receiver as well as switching functions and filters in the front end.
Each generation of wireless technology pushes the envelope for performance in terms of linearity, and RF power output as well as the continuous need for better and better efficiencies. Will GaAs be able to support 4G LTE terminals or will another compound semiconductor technology be required?
The final paper in this session will focus on a complete end to end GaN/SiC HEMT MOCVD process technology solution developed by the Fraunhofer Institute for power devices up to 20GHz.
SESSION 5a: COMPOUND SEMICONDUCTORS IN
INDIA
Chair: Yohei Otoki, Hitachi Cable
This session includes one talk by professor Dhrubes
Biswas from the Department of Electronics and Electrical
Communication Engineering, and Rajendra Mishra School of Engineering Entrepreneurship at the Indian Institute of
Technology. The presentation will cover the perspectives, opportunities, and future of compound semiconductor technologies in India.
39 2011 Compound Semiconductor MANTECH
SESSION 5b: COMPOUND SEMICONDUCTORS IN
Chair:
CHINA
Mariam Sadaka, Soitec USA
This session includes one talk by Dr. Morris Young, CEO of AXT, Inc. Dr. Young will talk about China’s fast growing role in the future of compound semiconductor technology and manufacturing. The presentation will focus on the key activities supporting the growth, such as contributions of the private and public sectors and the role played by technical institutions and universities.
Furthermore, different segments and geographic distribution of the compound semiconductor industry in
China will be reviewed along with some details of the growth projections for the coming 5 years.
SESSION 6a: PROCESS I –PLASMA PROCESSING
Chairs : Russ Westerman, Plasma-Therm, LLC
Papers in this section focus on improving the manufacturing performance of plasma deposition and etch processes used in compound semiconductor manufacturing. The first paper of the session by RF Micro
Devices discusses optimization of an in-situ clean used in conjunction with a plasma enhanced chemical vapor deposition (PECVD) process. Recipe changes applied to the in-situ clean process improved both tool up time as well as stabilizing wafer deposition uniformities between cleans. The second paper in the session from Global
Communication Semiconductors also looks at improvements to a PECVD process. This paper correlates
PECVD silicon nitride (SiN) film properties to metalinsulator-metal (MIM) capacitor performance. The paper also discusses improvements that more than doubled the process capability (Cpk) of the deposition. The last paper of the session, by Skyworks Solutions, examines damage mechanisms from plasma etching thin films on gallium arsenide (GaAs). The Skyworks work uses electrical measurements of a Schottky diode structure to explore the damage responses of typical plasma recipe parameters.
The paper also examines post-process approaches that can be used to mitigate plasma induced damage downstream of the etch.
SESSION 6b: GaN Epi
Chairs: Victoria Williams, CREE
Andy Souzis, II-VI Inc.
The GaN epi session will present a selection of papers addressing different challenges within GaN epi technology. The first paper by Guo, et. al from IQE RF
LLC will describe a study of AlGaN/GaN HEMT uniformity using different buffer and barrier layer
40 2011 Compound Semiconductor MANTECH
structures. The effects of two different types of back barrier layers, AlGaN and InGaN, as well as different substrate sizes, substrate polytypes, and barrier/cap structures deposited after the 2DEG, will be described as part of this study. The second paper, contributed by Faili, et. al from Group4 Labs, LLC and Air Force Research
Laboratory will present results from the fabrication of GaN on diamond HEMTs by transfer and bonding of an
AlGaN/GaN epitaxial layer on a CVD diamond substrate.
Diamond substrates are predicted to improve heat spreading in the gate region, increasing the potential for
GaN to reach its performance limits. Progress and technological challenges of this technology will be discussed in detail. The third paper, by Gu, et. al. of Evans
Analytical Group, concludes the session with a description of a method for rapid characterization of vertical threading dislocations in GaN. Scanning transmission electron microscopy (STEM) was used to reduce the complexity of this type of analysis and to identify the type and density of the dislocations.
SESSION 7a: PROCESS II - METAL
Chair: Travis Abshere, TriQuint Semiconductor
It seems that every year the diversity in topics, materials, and technologies presented at CS MANTECH grows.
However, it is heartening to see that the emphasis on manufacturing technology continues to be supported both within CS MANTECH and by the quality of papers submitted by the industry. As in years past Skyworks
Solutions has a strong showing in the Metals session, starting off with a study of backside wafer plating uniformity improvements from optimization of the anode design. The work was part of a 4” to 6” conversion, but the combined optimization of equipment and process involved in scaling up this technology provides excellent material to anyone interested in improved electroplating.
The second paper moves us over to evaporated metals with an emphasis on applying a broad based group of improvement techniques to increase both tool availability and product yields. The concepts of continuous process improvement and the value of cross functional improvement teams are clear winners in this effort to relieve pressure on a capacity limited toolset. The third paper is one of the excellent student papers submitted this year. From the University of Illinois (Urbana-Champaign) we have a topic that explores the complexity associated with clearing the area beneath an air bridge when dealing with the multiple epitaxial layers of an HBT. Our fourth and final paper continues with HBTs but brings us back to
Skyworks Solutions in an exploration of Collector contact optimization. This paper brings home one of the fundamental realities of compound semiconductor
41 2011 Compound Semiconductor MANTECH
manufacturing today – our industry is maturing and the low hanging fruit of the past is being replaced by incremental improvements with contributions from suppliers, materials, and improved understanding of the interactions between process steps.
SESSION 7b: HIGH-FREQUENCY GaN DEVICES
Chairs: David Meyer, Naval Research Lab
Robert Sadler, Nitronex Corporation
In recent years, there has been an increasing interest in developing GaN transistor technology for millimeter-wave applications such as monolithic microwave integrated circuits (MMICs). In order to achieve the high operating frequencies necessary for millimeter-wave amplification, novel device designs with laterally and vertically-scaled geometric dimensions are currently being investigated on a variety of substrates. Potentially offering the most financially viable solution, devices fabricated out of heterostructures grown on low-cost silicon substrates have begun to demonstrate performance metrics that rival transistors made on traditional substrates. This session contains reports on GaN high electron mobility transistors
(HEMTs) that operate at frequencies above 30 GHz. We start with an invited talk by Prof. Colombo Bolognesi, chair of the Millimeter-Wave Electronics Group at the
Swiss Federal Institute of Technology (ETH) in Zurich.
Prof. Bolognesi will survey recent results for latticematched AlInN/GaN HEMTs that enable the very thin barrier layers required for <100-nm gate lengths. These devices have demonstrated the highest bandwidths yet attained for nitride transistors, with f
T
= 205 GHz on SiC substrates and 143 GHz on high-resistivity (HR) silicon substrates. Prof. Bolognesi will compare this performance with results achieved for recessed-gate AlGaN/GaN
HEMTs on HR-Si substrates. This will be immediately followed by a paper from the same group covering the RF characterization of coplanar waveguides (CPWs) on
AlGaN/GaN heterostructures on HR-silicon substrates, at frequencies up to 110 GHz. The characterization shows that CPW’s on GaN/Si exhibit performance comparable to those on semi-insulating GaAs or InP, clearly demonstrating the suitability of GaN/Si technology for mm-wave MMIC applications. The next paper in this session, contributed by Chabak and co-workers from the
Air Force Research Laboratory and Sensor Electronic
Technology, will showcase electrical results from a study investigating submicron T-gate AlInN/AlN/GaN HEMTs on SiC. By using a 6 nm-thick, strained (15% In fraction)

on the small- and large-signal properties of this novel device. The last paper in this session will be presented by
Matsushita and co-workers from Toshiba Corporation and will discuss the effects of via layout on parasitic source inductance and frequency performance of GaN HEMT devices. Matsushita will also discuss Ka-band load-pull measurements of a four via-hole configuration that has produced saturated output power of 32.6 dBm (4.5W/mm), linear gain of 7.3 dB, and PAE of 41%.
SESSION 8a: PROCESS III- LITHOGRAPHY/BCB
Chairs: Chris Yousey, MicroLink Devices, Inc
Presentations in this section, from several leading GaAs IC manufacturers, describe a range of practical challenges associated with device lithography, planarization and the novel solutions that were developed to improve process yield and robustness.
The first paper of the session from Skyworks Solutions presents a new method to create sloped resist profiles by exposing with patterns that incorporate microstructures below the stepper optical resolution limit. This enables partial exposure of the resist around the designed features and localized control over the development rate. Sloped resist profiles are an important method in device fabrication to minimize abrupt step height changes. This presentation discusses the advantages of the new technique compared with conventional approaches such as thermal reflow or exposure defocusing.
The following paper from TriQuint Semiconductor presents a new trilayer resist electron beam lithography process used to form T-gates for GaAs pHEMT devices.
The new process improves process yield by reducing metal liftoff “stringer” defects encountered when using the conventional bilayer resist. Cross-sectional FIB-SEM images clarify the mechanism for defect formation, and
DC and final visual yield data validate the process improvements.
Next TriQuint Semiconductor presents a critical process issue encountered when using photo-definable BCB to encapsulate HBT and pHEMT GaAs MMIC circuits.
Intermittent wrinkling of the BCB dielectric was solved through a DOE that clarified proper exposure, development and baking parameters.
The final paper from Avago Technologies discusses the challenges of using BCB to planarize over topologies with widely varying pattern density. Local variations in BCB thickness can lead to shorts as well as incomplete metal via formation. Optical profiler measurements of BCB film
43 2011 Compound Semiconductor MANTECH
thickness over a complex circuit structure are compared with predictions from a model that is incorporated into a design-rule checker. Electrical test structures are also described that are used to characterize the process limitations.
SESSION 8b: SUBSTRATES
Chairs: John Blevins, Air Force Research Lab
Judy Kronwasser, NOVASiC
This session reviews recent progress in the development of wide bandgap substrates for high power RF amplification, power switching and light emitting diodes. Kyma will provide a comparison of many wide bandgap materials, both bulk and template, for nitride device applications, particularly LEDs. Hexatech will explore recent technological advances associated with bulk AlN growth and device fabrication. Dow Corning will highlight advances in scaling and quality improvement for their
100mm 4H-SiC substrates. The last paper of the session describes the success of the II-VI / Air Force Research
Laboratory / Missile Defense Agency joint initiative.
Improvements in 6H-SiC diameter, crystal quality, and producibility will be discussed.
SESSION 9a: MANUFACTURING
Chair: Chuck Duncan, RF Micro Devices
Compound semiconductors offer nearly limitless structural and elemental combinations which often create competitive advantage over existing scaled solutions. Although these advantages can create significant market opportunities, companies must be able to demonstrate capable manufacturing solutions with an eye toward continuous improvement in cycle time, performance, yield and cost.
Increased circuit complexity and integration demand improvements in basic manufacturing capabilities just to maintain historic yields. Manufacturing improvements are keys to the continued growth and sustainability of our industry and allow companies to maintain or even increase their competitive advantage once performance gaps begin to close.
This session includes a presentation on the reduction of manufacturing waste and environmental impact as well as three papers highlighting yield improvement solutions and techniques. The first presentation in the session highlights efforts at Sony Semiconductor Kyushu Corporation to reduce the waste and by-products associated with their wafer grinding process and to reduce the environmental impact of the GaAs grinding activities. The presentation will outline efforts to reuse waste water from the grinding process reducing demands on the factory high purity water
44 2011 Compound Semiconductor MANTECH
systems. It will also address efforts to reduce consumable components in the grinding equipment. In our second presentation from Avago Technologies, the presenter will outline strategies for the use of wafer randomizers to trouble shoot wafer yield issues. Borrowing from techniques implemented in high volume silicon manufacturing, wafer randomization techniques in use at
Avago help identify trends within single lots or lot to lot.
They also outline methods for identifying concerns in multi-chamber tools. Representatives of TriQuint
Semiconductor manufacturing facility will present an overview of techniques employed to reduce yield loss in their production process. While their resulting yield improvements are significant, the methodologies and problem solving approaches outlined are equally valuable as they demonstrate a solid framework and foundation for most any yield improvement effort. In the final presentation of the session, RFMD will describe efforts to reduce wafers broken during the backside processing of thinned wafers. Numerous process variables were explored to understand their impact on wafer breakage in a team investigation and problem solving environment.
SESSION 9b: DEVICE TECHNOLOGY
Chair: Kamal Alavi, Raytheon
The device technology session has four regular papers and one student paper, all having practical and relevant information for device engineers. The first paper, from
WIN semiconductor, discusses how to compensate for natural variations in an epitaxial layer structure through utilizing gate metal sinking in an E/D mode pHEMT process and thus achieve better consistency of pinchoff voltage of the EFETs. The second paper, also from WIN, details a 0.1 um pHEMT foundry process on 6” wafer for
V band applications. The process features Imax of 720 mA/mm, Vp of -0.9 V, fT of 135 GHz, Pmax of 850 mW/mm at Vdd=4 V, gain of 8-9 dB at 70-90 GHz, and
Fmin of 0.8 dB at 40 GHz. The third paper, from Hitachi
Cable, shows the methodology used to optimize buffer layer structure of high power MESFETs used in power amplifiers. The fourth paper, from Avago Technologies, details the optimization of Boron isolation implant doses and energies for a GaAs HBT device so that low junction leakage and high isolation resistance are achieved simultaneously. The last paper is a student paper from
Georgia Tech. It shows exciting device results for a GaN
HBT process. Collector current density of 19.8 kA/cm2 is achieved with a BVceo of 110V and knee voltage of <
2.1V.
45 2011 Compound Semiconductor MANTECH
SESSION 10a: EMERGING TECHNOLOGIES
Chair : Chanh Nguyen, Teledyne Scientific
The common theme of this session is “Beyond CMOS” or
“More-than-Moore”. We have four presentations describing novel approaches to extend performance and functionality over and above the traditional scaling of Si
CMOS by incorporating compound semiconductors. The invited paper from SOITEC reviews the latest developments in substrate engineering to integrate III-
V/Ge on Si, device architecture and challenges of this heterogeneous integration on the CMOS platform.
Integration of GaN and Si to form a hybrid wafer by wafer bonding technology is the subject of the invited paper from
MIT. Devices, circuits, and systems exploiting GaN/Si hybrid wafers will be discussed. The next invited paper from UCLA presents two alternative approaches to substrate engineering for compound semiconductor applications: the transfer of III-V templates and porous semiconductors for epi growth and device layer transfer.
The last presentation from University of Berlin discusses the integration of different technologies from the perspective of modular multi-functional technology development.
SESSION 10b: SIMULATION AND
Chair:
CHARACTERIZATION
Jon Abrokwah, Avago Technologies
Sharon Woodruff, Northrop Grumman (ES)
This session features five papers describing simulation and characterization research on GaN devices. The first paper by Takuji Yamamura and Kazutaka Takagi of Toshiba
Corporation reports on the difference in thermal design of
GaN and GaAs FETs. Simulations and measurements show that while GaAs device thermal resistance depends on total gate geometry, pitch and substrate thickness, GaN
FETs fabricated on SiC have much less dependence, due to the 6X greater thermal conductivity of SiC compared to
GaAs. Thermal resistance of AlGaN/GaN HEMTS depends mostly on die size.
The second paper by M Bernardino et al. of University of
Parma, Italy discusses modeling of the impact of boundary conditions on AlGaN/GaN HEMT self-heating. The effects include die-attach, finite backside heat-sinking, thermal boundaries between GaN and SiC and the thermal boundaries of the top metallization.
After that A. Christou of University of Maryland describes using FMEA (Failure Modes and Analysis), to review the primary failure modes of GaN based microwave devices, indicating that trapping is the dominant mechanism for
46 2011 Compound Semiconductor MANTECH
device degradation and failure. They discuss effects of piezoelectric charges, tensile strain, and defect formation.
In addition, models to predict electrical behavior, such as current collapse, power soak, DC and RF degradation are discussed. Next by S. A. Chevtchenko et al, of Ferdinand-
Braun-Institute, Germany, discuss their investigation and reduction of gate leakage in AlGaN/GaN HFETs through optimization of the process of the first and second SiN passivation dielectric to reduce stress.
Finally, N. Killat et al. of University of Bristol and MIT present a lucid description of electroluminescence capacitance measurements and simulation to show impact ionization phenomenon in InGaN/GaN HEMTs.
SESSION 11a: LED
Chair: Drew Hanser, SRI International
Shyh-Chiang Shen, Georgia Tech
This session will start with an invited presentation describing the manufacturing and applications of the highbrightness InGaN and AlInGaP light-emitting diodes
(LEDs) by Osram Opto Semiconductors. This presentation will provide an overview of these technologies and discuss key challenges of low-cost manufacturing. Another invited talk will follow with a focus on optoelectronic devices grown on nonpolar and semipolar free-standing (FS) GaN substrates. In this talk, researchers from the University of
California at Santa-Barbara will present a summary of material and device developments for laser diodes and
LEDs on several orientations of non-polar and semipolar free-standing GaN. In the second half of the session, a paper concerning the characterization of reverse-biased electroluminescence of InGaN/GaN LEDs and a student paper on InGaN/GaN nano-rod LEDs using a top-down etching processes will be presented.
SESSION 11b: RELIABILITY
Chair: Peter Ersland, M/A-COM Technology Solutions
Chang-Hwang Hua, WIN Semiconductors Corp
This year’s reliability session includes papers on both active and passive circuit elements, with relevance to both high volume consumer applications, and leading edge high voltage technologies. Our first paper discusses approaches for the reliability qualification of a Bi-HEMT process at
TriQuint. Since the failure mechanisms for HBTs and pHEMTs may be quite different, qualifying a technology that incorporates both device types requires careful planning and development of structures to investigate not only each device type individually, but the interaction of
47 2011 Compound Semiconductor MANTECH
these two process technologies on a single wafer. The authors review the wafer scale reliability tests performed, and describe the results of these tests. Our second paper addresses a topic of importance to both reliability and design engineers – thermal performance. A variety of design and process options are investigated by these authors from Skyworks, including different top side metal thicknesses, the location of both through wafer vias and backside thermal vias, and various materials choices.
Tradeoffs are described between optimizing thermal performance and minimizing parasitic capacitance for these devices. The third paper in this session describes work performed at WIN Semiconductor to assess the impact of collector design and layout on HBT ruggedness.
The authors’ results show not only the impact of these factors on Safe Operating Area (SOA), but on device electrical performance as well, and indicate the importance of characterizing SOA on large transistor cells. Our fourth and final paper addresses the effect of layout, dielectric thickness, and the nitride deposition process on capacitor reliability, particularly for use in GaN MMICs. The authors from the University of Ulm and United Monolithic
Semiconductors (UMS) present ramped voltage reliability test results that indicate a significant difference in the predicted life time of the three different nitride deposition processes assessed in this study.
SESSION 12a: FAB MANAGEMENT &
Chair:
TECHNOLOGY TRANSFER
Arnold Chen, Infinera
This year the fab manufacturing and technology session will have two papers that focus on process transfers and two papers that discuss factory management. The session will begin with an invited talk from Cobham Sensor
Systems in which they discuss the unenviable task of shutting down and physically relocating their entire MMIC wafer fab operation. How they managed to go from shut down to resuming production in a mere eight months you’ll have to attend the talk to find out. The second talk in the session is from Freescale Semiconductor (in partnership with WIN Semiconductor), where they will discuss the methodology they used and the challenges encountered transferring their 12V PHEMT technology from their internal fab to WIN Semiconductor’s foundry service. In the third paper of the session, we will learn from the experiences of GCS concerning how they have successfully managed to run optoelectronic devices on a qualified RFIC manufacturing line. One of the more interesting challenges they solved is how they managed to run a single line with multiple wafer sizes. Last year’s plenary session included talks on “green” manufacturing.
48 2011 Compound Semiconductor MANTECH
It’s only fitting that we continue this trend this year. In the session’s last talk, RFMD discusses the results of a several green initiatives. These include reclaiming precious metals, recycling or reclaiming solvents as well as reducing the use of ultra pure water.
SESSION 12b: POWER SWITCHES
Chair: Scott Sheppard, CREE
The Power Switch session contains two invited, one student and one regular paper. Each paper addresses different aspects of the use of wide bandgap compound semiconductors for high-power devices. The session begins with an invited paper. Peter Friedrichs of SiCED
Electronics Development gives a survey on SiC power device development and prospects of commercialization over the past 10 years. The second paper will be a student presentation by Tsung-Ting Kao of Georgia Tech who reports the high voltage device performance of
AlGaN/GaN Heterojunction Field Effect Transistors
(HFETs) grown on Si substrates with low specific onresistance and high breakdown voltage. Next in an invited talk, Tsutomu Uesugi of Toyota central R&D Laboratories,
Inc. will compare the lateral structures and the vertical structures of the GaN on Si power devices and discuss their application to future power devices. Finally, Mrinal Das of
Cree, Inc. gives a very comprehensive overview of commercially available silicon carbide power devices. It will include a treatise on SiC JBS diodes and future power switching commercial devices in SiC.
SESSION 13: INTERACTIVE FORUM
Chairs: Thorsten Saeger, TriQuint Semiconductor
Thomas Roedle , NXP Semiconductors
Suzanne Combe, TriQuint Semiconductor
Following the tradition initiated in 1994, the Interactive
Forum is a session devoted to promoting the open exchange of ideas and information. This session allows for discussions and face-to-face meetings between the authors and conference attendees. During the Interactive Forum, all authors of presented papers will be available to answer questions and further discuss their technical results. All your questions you did not dare or manage to ask during the oral sessions can now be discussed with the authors in an informal setting.
In addition, this Forum will be the only time at the conference where papers that have been selected for the
49 2011 Compound Semiconductor MANTECH
Interactive Forum only will be displayed. These papers demonstrate in a beautiful way the true nature of CS
MANTECH as the integrative conference in compound semiconductors: participants from industry and academia; from Asia, Europe and North America; presenting their valuable results generated from a broad range of compound semiconductor materials as InP, GaN, GaAs, SiGe, SiC and Diamond. Topics as diverse as optics, microelectronics and equipment-engineering are covered from an experimental as well as simulation viewpoint. In short: CS
MANTECH at its best!
Attendees of the Interactive Forum will vote for the best poster, and the winning author will receive the Best Poster
Award in form of a mini LED projector.
