TSMC Facing Yield Issues in 40nm Process Again

Chipmaker TSMC is having yield problems with their 40nm process again, according to DigiTimes. TSMC’s CEO vows to have the issues resolved within the quarter. Sounds familiar? That’s because Steve reported the original problem back in July, though the company said the issues were fixed back then.

Main customers for TSMC's 40nm processes are GPU vendors AMD, which recently launched its new 40nm-based Radeon 5870 series, and Nvidia, who is scheduled to launch its 40nm-based GT300 series of chips in December, according to previous reports. TSMC's recent issues may impact the shipping schedules of the GPU vendors, market watchers commented.
