CHIPMAKER TSMC said it has improved yield rates on its 40nm manufacturing process and everything is on a par with the older 65nm process.
According to Digitimes, Mark Liu, senior VP of operations at Taiwan Semiconductor Manufacturing Company (TSMC) said at a company event that the chamber matching problems that had blighed yield rates for the last quarter have now been fixed.
He did not say much else, but the low yields have resulted in problems for several of TSMC's customers and could mean that some will have to delay product launches while the chipmaker clears up its backlog.
TSMC opened a new factory building named Phase 5, which is part of the company's Fab 12 located at the Hsinchu Science Park in Taiwan. Once Phase 5 is operational it will be used for volume production of 28nm products in the third quarter of 2010.
The outfit is also planning to build Phase 6 of Fab 12, which mainly will be used as its 22nm production base. Liu said all this building is needed to keep up with demand for chips in the coming quarters. µ
