Amkor Announces FusionQuad(R) Technology Licensed to ASAT

Amkor Technology, Inc. (Nasdaq: AMKR) today announced ASAT Holdings Limited (Nasdaq: ASTT) has entered into an agreement to license Amkor’s FusionQuad® package technology. This agreement will enable ASAT to manufacture packages based on Amkor’s FusionQuad® technology platform.

“The market has been seeking a low cost package technology to better serve applications in the 150 to 350 pin count range. We believe FusionQuad® technology meets these cost sensitive requirements and also provides improved thermal and electrical performance for advanced applications. We are in the process of deploying this technology to meet challenging ASIC requirements in hard disk drive, multi-functional printer and HDTV applications,” said Jim Fusaro, Amkor’s corporate VP responsible for wirebond products. “Amkor is pleased that ASAT also sees applications for this technology and we believe multiple sources of supply will facilitate broader adoption of this innovative new package platform,” added Fusaro.

“ASAT and Amkor have enjoyed benefits from our licensing agreements in recent years and we are pleased to extend that cooperation to include the FusionQuad® technology. Growth in QFP packages has been slowing as the technology has matured, with little innovation over the past few years. We believe the FusionQuad® technology will inject new growth in the QFP family and is an attractive extension to our current package offerings,” said Jeff Osmun, ASAT’s President.

FusionQuad® technology integrates bottom lands within a standard QFP package outline to enable doubling of the interconnect density, improved signal integrity for high speed signals and higher power dissipation.
