Cypress To Improve Manufacturing Yield Using WaferYield Technology

8/21/2002 - Cypress has expanded its non-exclusive commercial license agreement to use WaferYield’s WAMATM technology. WAMA technology is expected to improve the yield, throughput, and profitability of Cypress’s wafer fabrication operations, which support its manufacture of integrated circuits.

"In this challenging economic climate, all capital expenditures are highly scrutinized and need to be strongly justified," said Christopher Seams, Cypress EVP of technology and worldwide manufacturing. "It makes much better sense to find ways to improve the yield of existing equipment. By expanding the use of WAMA technology and implementing it in all of our fabs, we look forward to seeing greater manufacturing efficiencies."

WAMA tools are based on WaferYield’s patented, proprietary wafer-mapping WAMA technology. Each module targets a different aspect of the wafer fabrication process. WAMA modules are designed to increase gross dice, maximize good dice, maximize fab throughput, and maximize return on investment.

"We view Cypress’s multiyear corporate license agreement as a vote of confidence for WAMA technology," said Eitan Cadouri, WaferYield CTO. "We’re looking forward to exhibiting how WAMA tools deliver their benefits without requiring Cypress to change its processes or redesign its products."
