San Jose, CA, March 21, 2001 -- For the third year in a row, Analog Devices, Inc. (NYSE:ADI) has awarded TSMC its ADI Supplier Award for overall excellence in semiconductor production. The ADI Supplier Award is based on an exacting supplier rating program that includes criteria such as on-time delivery, cycle time, yield, quality, and responsiveness. A specially designed crystal trophy was presented to TSMC in recognition of this significant accomplishment.

“TSMC is the lead foundry service for Analog Devices Inc., producing literally millions of devices for the company annually,” said Dr. Ed Ross, president of TSMC North America. “Together, the two companies have pushed the process envelope and expanded the market for foundry-based semiconductor technology. We value this award as recognition of a truly significant partnership.”
