Yony,

Oh great yield expert.

Perhaps you could help us understand a little bit more.

1. You must be aware that yield is a function of die size.

So wrt to recent chips like the HP 8500 chips.
These yields should naturally be low due to large die size.
Does this mean that HP's 8500's are doomed and will be highly unreliable.
Should we be calling Platt and telling him about these major reliability threats.

2. Also Intel is putting massive cache memories on chip.
So these chips will be much larger than chips with smaller caches.

Are these new Intel chips a long term yield/reliability threat?

3. Intel is using redundancy to improve yields.

Basically a defective portion of the chip is bypassed and a good portion muxed in it's place. But these defects are still there and they can grow and fester can they not. Could this cause long term reliability problems.

4. As you are probably aware yields are tuned over time.
When new products come out yields are low and then gradually improve.

Should we be designing in the latest Intel 450 Xeons as they are at high end of yield cure. How about all those memory chips as they move up the technology curve.

Regards,

Kash
