UMC gains from TSMC 28nm supply issues

United Microelectronics Corp. (UMC) may be the big winner in 28nm chip supply shortages of its biggest rival, Taiwan Semiconductor Manufacturing Co. Ltd (TSMC), said a report by the Taiwan Economic News.

As the second largest pure-play foundry company, UMC has 80 tape-outs for the 28nm manufacturing node, the report said referencing unnamed industry executives. UMC entered production in the first quarter of 2012 although this was with a conventional polysilicon/silicon oxynitride gate stack rather than the high K metal gate (HKMG) stack used by TSMC at 28nm.

Inadequate volume to meet demand at TSMC has prompted comments from some of its customers and others, including Qualcomm. Customers have said they are seeking capacity elsewhere.

Texas Instruments is making its OMAP 5 on 28nm at UMC, while Qualcomm has asked UMC to make integrated baseband chips, the report said. To cope with demand UMC is planning to increase manufacturing capacity at its Fab 12a wafer fab in southern Taiwan to add 50,000 to 60,000 wafer starts per month at the factory, the report added.
