EDINBURGH, Scotland--After expressing its skeptical views about the Chinese foundries, Wolfson Microelectronics plc Tuesday (May 25) said it has contracted with China's CSMC Technologies Corp. for wafer foundry services.
Wolfson has received the first wafers from CSMC's 150-mm fab facility at Wuxi, China. The qualification of the CSMC-Tech fab was announced back in April.
"Before entering into this agreement, we evaluated CSMC-Tech rigorously, and we believe that they are able to meet our high expectations of quality and performance," said John Urwin, operations director for chip maker Wolfson, in a statement.
"We have received the first wafers from CSMC-Tech," he said. "Tests show that they exceed our performance and high quality expectations thus enabling us to ramp up production immediately across a number of products."
In January, David Milne, chief executive officer of mixed-signal chip provider Wolfson, said he was looking at Chinese wafer fabs as alternatives to the company's two main foundries, but that some of the China foundries are not able to cope with the mixed-signal circuits.
Wolfson, a company that has found success by concentrating on mixed-signal integrated circuits for the consumer audio, digital imaging and portable equipment sectors, uses Korea's Hynix Semiconductor Inc. and Singapore's Chartered Semiconductor as its main suppliers of foundry services (see January 21 story).
