TSMC Enters into 0.35um SRAM Volume Production

Hsinchu, Taiwan, June 19, 1996 -- Taiwan Semiconductor Manufacturing Company Ltd. (TSMC) announced today that it has begun to offer the 0.35um SRAM manufacturing process to its customers. TSMC is the first company in the world to provide volume production of 0.35um SRAM technology.

Mr. Don Brooks, president of TSMC, stated that since the end of last year when 0.35um design rules were first made available, the company has been working closely with its customers to pilot the production of new products designed to employ the 0.35um technology. These pilot products have successfully passed the most stringent tests and have achieved a sort yield higher than 90%. Mr. Brooks was pleased to report that these efforts have resulted in 1M Synchronous SRAM going into mass production considerably ahead of schedule.

"The 0.35um SRAM process developed by TSMC has a new and aggressive cell structure", said Dr. John Y. Chen, vice president of R&D at TSMC, "With the new structure we have achieved nearly 60% reduction in cell area compared to previous generations of SRAM. As a result, the number of gross dice per wafer can be doubled. We believe this new technology will help customers maintain profitability in the increasingly competitive SRAM market." Through the development of this advanced manufacturing process, TSMC has created a win-win situation where customers can benefit from the reduction of cost per dice, while TSMC can expand its business opportunities.

The 0.35um SRAM manufacturing process was presented in a recent TSMC technology workshop organized for customers in the US. Everyone at the workshop was impressed, not only by the cost-reduction performance of the new technology, but also the early achievement of volume production accomplished by TSMC. It is worth noting, said Dr. Chen, that the 0.35um SRAM technology will also help logic customers who want to embed SRAM memory blocks in their designs.

Newer generation microprocessors such as Pentium and Pentium Pro require higher speed cache memory. With its high speed of 3 nano-seconds, the 0.35um Synchronous SRAM will soon become a mainstream SRAM product used in high-end PC applications. In addition, the 128k x 8 SRAM used in high speed modems will be dominated by products using the 0.35um SRAM process.
