TSMC: 40nm issues resolved
 

TSMC's Senior VP of Operations, Mark Liu, has mentioned that TSMC's troubled 40nm process is now of the same quality as the mature 65nm process. The chamber mismatch issue which dropped the yields of the HD 5800 series to a reported 40% have now been resolved, and yields are recently rumoured to be between 60% and 80%.

Nvidia's much anticipated GF100 is also based on the same TSMC 40nm process. With constant rumours of disastrous yields, delays after delays, an improvement in the process is just what Nvidia needed. Of course, these yield increases are reflected and evidenced by the sudden widespread availability of the HD 5800 series around the turn of the year.
