Grace Win Marks Continuation of Asyst's Total-Automation
Market Leadership in Emerging China Market

FREMONT, Calif.-July 31, 2002-Asyst Technologies, Inc. (Nasdaq NM: ASYT), a leading provider of integrated automation solutions that maximize the productivity of semiconductor manufacturing, today announced it has received a multimillion-dollar order from Grace Semiconductor Manufacturing Corp. (GSMC) of Shanghai, China. Asyst is the leading provider to China of standard mechanical interface (SMIF)-based isolation products for semiconductor-manufacturing automation, having won essentially all of this business to date from the region's two other semiconductor-manufacturing customers.

Dr. Winston Wong, CEO of GSMC, said, "GSMC is committed to being among the most efficient and competitive manufacturers of semiconductors. We selected Asyst because of their proven market-share leadership in 200mm isolation and work-in-process management products and their strong record of support and service throughout Asia."

Ken Leung, president, Asia-Pacific, for Asyst, said, "We are pleased and proud that Grace Semiconductor has chosen Asyst as its automation partner for its first fab. This win further validates our leadership position as the primary supplier of SMIF products to the China market."

Asyst is the world's leading supplier of 200mm wafer isolation (SMIF) and wafer-lot tracking technology, with an estimated market share in excess of 80 percent worldwide. In the foundry market, Asyst shipped its first SMIF products to a major Taiwanese foundry in 1989, and since that time, essentially every major foundry in the world has adopted the company's technology. In early 2001, the company received its first order from China, for the first China fab established by a major North American microelectronics manufacturer.
