Re: Metal gates work, and deliver benefits. But this does not come for free. It is the reason Intel added one fab from its plan of three 45nm fabs last year to four.
So in other words, you expect Intel to be producing no more products at 45nm than they are currently producing at 65nm, but they are requiring approximately 33% more wafer starts (4 fabs instead of 3), just to account for poorer yields?
I just want you to be specific, and be sure that with all the new product lines Intel is introducing, including Silverthorne, Larrabee, and possibly others, that you are certain there is no other explanation for the addition of a 4th 45nm fab, other than to account for bad yields on Intel's HK/MG process.
