Wbmw -

I notice that a die the size of Barton (~10mm/side) would need to have a defect density of 2.0/cm^2 in order to get the yield in that range. Could it possibly be that bad? I would have figured it could be about 0.5/cm^2 for foundries. What's your comment?

I agree. ~0.5/cm2~ would have been my estimate too. The poor yields described most likely include parts scrapped for speed as well as hard defects, unless the rumors Yousef kept referring to about problems with low-K dielectric are as bad as they seemed.... If they are true then you might see AMD changing their design rules and redoing the layout resulting in a larger die. Didn't AMD rework Barfon and the die size went up???
