A report in Taiwanese newspaper the Commercial Times said that United Microelectronics Corp (UMC) will build a 12-inch fab in the Tainan science park. UMC had originally intended to build an eight-inch wafer fab but increased demand has caused it to bring forward its plans. The company now has five fabs and last year bought Nippon Steel Semi. Meanwhile, Intel plans to make a decision very shortly about its own 12-inch wafer plans. ®
