Packaging has acted as a space and electrical transformer providing protection for the contents of the package and access for power and signals to and from the outside world. Smaller form factor • Without package substrate, a thinner package can be achieved. • Fan-out package integrates different chips into a single 2D package, achieving volume thinning SiP (System in Package) technology, With the demands for smaller, more efficient, and highly durable ICs will only increase over time as consumer demand for thinner and lighter electronics grows. As such, package technology has gone from lead frame, flip chip package to fanin wafer level packaging which helped to decrease chip size and thickness whilst effectively lower fabrication cost. Greater efficacy • The RDLs are routed inward and outward, enabling thinner packages with more I/Os. • Using RDL to connect chips of different functions, the functionality will increase by integration into a single package. Integrate more functions TREND OF INNOVATIVE ADVANCED PACKAGING Due to the demand of consumer electronics products for portable and multi-functionality, the development of microelectronic is forced to reduce the size and costs, to raise high performance. However, the semiconductor packaging industry is faced with the dilemma of being unable to include the ever increasing demand for higher I/O count in the given microchip size to increase device efficacy for consumer electronic products. Not only system-in-package (SiP) but also more advanced packaging technologies in the future are tending toward using multi-die heterogeneous integration and end-use in consumer, high-speed computation, and profes sional applications. Thus, the development goals of advanced packaging tends to: • Increase the value of a semiconductor product • Adding functionality • Maintaining/increasing performance while lowering cost • Decrease chip/package thickness IC a PCB Lead frame IC PCB Flip chip packaging IC 0.7a PCB Fan-out wafer-level/panel-level packaging However, fan-in wafer-level packaging still faced great challenges with the vast advances of end products. (1) Bumping is limited to the die size while continuing scaling down chip size. (2) The assembly cost gets higher while decreasing solder ball size. So, it is difficult and challenging for fan-in wafer-level packaging to increase more and more I/O counts due to the limit of the die size and the constraint on the cost of bump formation process while shrinking bump size. Therefore, the packaging market tends toward more advanced fan-out package.

There are two fan-out packaging technologies: Fan-Out Wafer-Level Packaging (FOWLP) and Fan-Out PanelLevel Packaging (FOPLP). Though the technical uses and applications are different, both can achieve thinner appearance for the final product. However, the cost of FOPLP is lower than that of FOWLP, making it the highest profile advanced package technology in recent years. CAGR in revenue for the advanced packaging industry may reach 7 % from 2017 to 2023 The advanced packaging market would reach about 39 billion USD in 2023.

BOTH TECHNIQUES CHANGE THE CONNECTION AND FABRICATE METHOD IN ORDER TO INTEGRATE HOMOGENEOUS OR HETEROGENEOUS CHIPS INTO A SINGLE PACKAGE. PANEL-LEVEL PACKAGING (PLP) IS ONE OF THE LATEST PACKAGING TRENDS IN MICROELECTRONICS, DEVELOPIG TOWARDS LARGER SUBSTRATE FORMATS. THE PUSH IS BEING DRIVEN BY PERCEIVED COST ADVANTAGES AND PRODUCTIVITY BENEFITS, AS PANELS ALLOW FOR PARALLEL PROCESSING OF MORE UNITS DURING THE SAME PERIOD OF TIME. Multi-Chip module packaging is an important facet of modern electronic miniaturization and microelectronic systems. It was designed for multiple integrated ICs to facilitate their use as a single package. This is considered a way to extend the "Post-Moore's Law" era. All mounted dies are KGD Fan-out package is the prevailing technology in advanced package. Its process: (1) Dicing a wafer. (2) Mounting known good dies (KGD) on carrier for molding. (3) RDL and solder bump formation. (4) Separate molding and reusable carrier. (5) Package singulation. This technique not only creates more I/O contact on package by fan- Substrate-less package out, it also reduces package volume and accomplishes homogeneous or heterogeneous chip integration. Therefore, chips are able to have higher performance and chip makers are able to lower the overall fabrication cost, while also simplifying the process steps and lowering the error rate. Homogeneous or heterogeneous The development of low density fan-out, platforms to encompass the requirements of potential new applications such as the 5G, AI & IoT. Fan-out continuously moves towards more and more homogeneous or heterogeneous multi-chip module integration into a single package. Thus, the larger fan-out package size will be the trend to achieve a more complex form of multi-chip integration to have more powerful performance. multi-chip module integration KGDs are attached to the carrier By using RDL process as foundation, The homogeneous or heterogeneous and then encapsulated in an epoxy drawing the needed RDL from the integration of multi-chips into a single molding compound. By completing die does not require a substrate, nor fan-out package could significantly save the following processes, e.g. Cu RDL, does it need a wire-bond, and the development time and cost comparing bump formation, carrier debonding, package thickness can be decreased. to SoC (System-on-Chip). and package singulation, etc., the fan- If forms multiple dies simultaneously, out package can be attained. the package can have multiple or even several dozen times more functions; this reduces the package wafer thickness when multiple chips are stacked! Known good die Furthermore, simplifying the fabrication process also lowers material costs. IC Substrate PCB Transparent glass Transparent glass, or circuit board or semiconductor materials * Carrier shape could be round or square, and its material could be glass, transparent glass, or other semiconductor materials FOPLP is attracting most attention as it brings economies of scale due to the large size of the panel and higher carrier usage ratio of 95 %. The ratio is much higher than that of wafer size FOWLP (carrier usage ratio of 85 %), and enables highervolume production of large packages. Currently, FOPLP is based on two major technologies: FPD and PCB production process and equipment. PCB Flip chip package EMC (Epoxy Molding Compound) V.S. IC 1 IC 2 IC 1 IC 2 PCB Fan-out package PCB On the downsizing circuit board, chip package size decreases, but all chips are still able to be integrated and thereby decreasing the area taken up by the circuit board, which also decreases the size of the end product. On the other hand, the reduced area on circuit board can be used for other electronic components. FOPLP technology not only supplies end products with higher efficacy, it also provides higher cost-efficiency. attracts players with many different business models, including outsourced semiconductor assembly and test (OSAT), integrated device manufacturers (IDMs), foundries, substrate manufacturers and FPD players. They perceive an opportunity to enter the advanced packaging business via fan-out technology. Semiconductor manufacturers Take the IDM and foundry for example: by integrating with the packaging, it is a beneficial commercial model to provide an entire chip package. In terms of packaging manufacturers, they can apply their existing experience to quickly incorporate FOPLP technology. The aim of investment is to find its potential cost benefit and to enhance product competitiveness. PCB and FPD manufacturers Simultaneous design and development of chip, package, and PCB are becoming more important. The lithography processes tools that have been developed for the production of printed circuit boards and flat panel displays can be applied to the FOPLP RDL process on large rectangular substrates as well. PCB and FPD manufacturers are able to reduce manufacturing costs by utilizing tools and process know-how. 600 x 600 mm carrier 500 x 500 mm carrier 300 x 300 mm carrier 300 mm wafer Higher carrier usage ratio, higher manufacturing efficiency In panel processing, the number of dies populated on a panel is much greater than the number of dies populated on a wafer. Productivity increase that can be expected: The 300 mm square carrier corresponds to IC 3 From 2018 to 2023, the CAGR of FOPLP is expected to reach more than 70 %. The estimated overall market size in 2023 will reach 279.3 million USD*. This 1.4 times the 12" wafer carrier. The 600 mm square carrier corresponds to * Data source: Research institute Yole Développement 5.7 times the 12" wafer carrier. 6 | FOPLP PRODUCTION SOLUTIONS | MANZ AG TOTAL PRODUCTION SOLUTIONS WITH DIVERSE TECHNOLOGICAL EXPERTISE MANZ RDL PROCESS PRODUCTION SOLUTIONS Wet chemistry Al or Cu pad Lithography process tools for high-density RDL process: Cleaning / developing / etching / stripping / electroplating Vertical or horizontal types In-line or batch types Manz FOPLP Solutions IC IC adhesive known good die carrier known good die Polymer protective layer coating molding IC carrier Molding known good die Modular solutions to automate production Total integrated solutions including wet chemistry, laser, and testing tools.
