How do you define "good yields?" A post by our good friend Elmer Fud, that he made on the Raging bull site, seems to indicate that Intel has redefined "good yields" to mean anything better than 30%. He may have accidently let a little inside info slip out. 140 217mm2 areas fit on an 8" wafer. Taking into account edge loss, that drops down to a little more than 90 good die. Elmer states that anything better then 30 good die would be above "my model of industry standard wafer yields based on die size and defect density." So, it may be that Intel's getting 40% yields, and telling itself internally that those are "great news!" If they'd been expecting 70% (or better) yields, it would go far to explain their present shortfall in production. ragingbull.lycos.com ragingbull.lycos.com Message 16671585
