Taiwanese foundry UMC
denies rumors that the company is having yield problems with its 65nm process. However, the company did add that shipments have fallen behind schedule due to a lack of capacity at its 300mm fabs.
United Microelectronics Corporation (UMC) has responded to recent speculation indicating its 65nm yield problems have affected shipments to Xilinx. UMC asserted that there are no concerns over its 65nm yields. However, shipments have fallen behind schedule due to overloaded capacity at its 12-inch fabs.
Chi Tung Liu, CFO of UMC, said that Xilinx had notified UMC about its recent move to adjust revenue guidance for April-June 2009. UMC's 65nm process is mature enough to provide sufficient yields, Liu claimed, explaining that the foundry is seeing full utilization at its 12-inch facilities. UMC will be working out solutions to reduce its cycle time in order to satisfy customers, Liu added.
