PRESS RELEASE

Global Communication Semiconductors, Inc. (GCS) Announces DHBT InP Process Development.

GCS, a pure play compound semiconductor foundry, is now offering DHBT InP.

December 18, 2001, TORRANCE, CALIF. - - - GCS, Inc. (Global Communications Semiconductor, Inc.) a pure-play compound semiconductor wafer foundry announced today that it has made a significant advancement in it’s proprietary InP (Indium Phosphide) HBT foundry services by adding a DHBT process.

"With our InP SHBT process we have already been able to address a number of 40Gb/sec OC-768 applications with a Ft of >160GHz, Fmax of >180GHz and a BVCEO of >3V" remarked Chanh Nguyen, CTO of GCS. "However, for power amplifiers and modulator drivers, a higher BVCEO is desirable. Our DHBT InP process yields a BVCEO of >8V with a Ft above 150 GHz at a low current density of 1 mA/µm2. This new DHBT process also takes advantage of the GCS low-loss interconnect technology GCS developed for high-speed circuits." continued Dr. Nguyen.

"Now with our new proprietary DHBT process technology, GCS can offer flexibility of both SHBT and DHBT InP foundry services to our customers to address their demanding IC performance requirements." commented Owen K. Wu, CEO and President of GCS. As the only pure-play InP foundry, GCS continues to play a pivotal role to assist companies to bring 40Gp/s components and 3G power amplifier products to market. Our optoelectronics group also recently announced breakthroughs in 1.31 and 1.55 micron InP based PiN Diodes. By combining our optoelectronics and InP HBT process technologies, GCS can address OEIC (Opto Electronic Integrated Circuit) applications. We are now beginning to engage with companies that are interested in targeting OEIC applications." Continued Dr. Wu.

Global Communication Semiconductors Inc., based in Torrance, California, an ISO 9002 certified company, provides compound semiconductor foundry services to the wireless telecommunication and high-speed networking industries. GCS currently offers foundry service for both InGaP and InP HBT processes and provides optoelectronic foundry services for PIN diodes used in the fiber optic communication market.
