Thanks for the clarification, Maxwell. What does "your numbers" translate to in "defects per sq cm"? Quick calculations of 5 defects per layer times 20 layers with maybe half doubling up gives me 5x20x0.5=50 defects. [1-50defective dice / 115 die/wafer](x100%) = 57% which is close to your numbers, thus reasonable. It seems to fit a model for the industry norm if I go out and look for a foundry to build a chip we design at my day job.

My understanding was that Intel was much better than the industry norm at making good clean rooms and keeping their machinery from causing defects and thus they have lowered this number from 5 defects per layer to something much to the envy of AMD (and others). I guess you are saying Intel isn't that much better than the industry norm?

Maxwell - Re: " If he say that Intel achieves 90%+ consistently on their PII then he is full of shit."

You have obviously entered a panic mode. Please change your underwear.

I have never claimed that Intel's Pentium II yields are "consistently 90%". You, however, seem quite fearful that perhaps Intel's yields are that high.

For Intel's 0.35 µ process, yields are well above 70%.

For Intel's 0.25 µ process, yields are also above 70%.

You, however, are free not to believe these numbers. I would expect nothing less of you.
