The times correspond very well with my data for volume production.
Just curious, are rocket-lots out of fashion for engineering wafers nowadays?

I'll accept the nit pick... it is good data.
Remember that AMD is doing 9 metal layers which does add some to the TPT. I did not want to muddy up the explaination, which would have stretched it to pages, by talking about rocket lots, the fact that some changes happen part way through the line, and what not. The reality is, it takes time to get this done.

BTW, The last time I was in a fab was Fab 7 in Abq, around 1984. I was playing yield manager at the time. I am sure things have changed quite a bit since then:-)
