THE SEMICONDUCTOR MARKET HAS ITS APPLICATION FOUNDATION ROOTED NOT ONLY IN TRADITIONAL PC AND
3C APPLICATIONS AND IS NOW VENTURING INTO IOT, BIG DATA, 5G COMMUNICATIONS, AI, AUTONOMOUS CARS,
AND SMART MANUFACTURING. SEMICONDUCTOR CLIENTS DEMAND SLIMMER FORM-FACTORS, LOWER POWER
CONSUMPTION, AND LOWER CHIP COSTS. THIS MAKES PACKAGING TECHNOLOGY EVEN MORE IMPORTANT.

Integrated circuit (IC) packaging is the
final stage of semiconductor device
fabrication. 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

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. An overall of

Fan-out package technology drastically
simplifies the complex process steps and
reduces material use, whilst effectively
lowering the overall production cost.
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.

packaging industry may reach 7 %

Fan-out packaging is now
an integral part of the portfolio
At the heart of innovation:
FOPLP technology
THE WAY TO MINIATURIZE THE PACKAGE FORM FACTOR BY FAN-OUT PACKAGING TECHNOLOGY IS TO
CONNECT DIFFERENT FUNCTIONS OF THE CHIP TO THE PASSIVE COMPONENTS BY RDL, OR TO FABRICATE IC
WITH 3D STRUCTURES. 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-

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.

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.

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

for the production of printed circuit

process know-how.
