Ref- <Do you think it is the baggage that goes with the 'notched' gates that is causing the yield problems>

The disappointing Coppermine availability has led to all kinds of speculation regarding Coppermine process yield problems.

My inferences:

The Coppermine design problem ( slow speed) surfaced last June. To improve speeds Intel quickly attached a new process module with notched gates and faster transistors to the existing 0.18 micron process.

Unfortunately with no significant manufacturing experience on the new process ,[ the earlier 0.18 micron process was running on a pilot line for more than 9 months+], Intel took the prudent approach of ramping the process slowly and starting only a limited number of wafers [ < 10%] on the new process. Apparently Intel has delivered 3million+ Coppermines, which indicates reasonably equivalent yields to the earlier products.

Shortly a design change will be in manufacturing, which will enhance speeds significantly. So in Q1 there should be more and faster Coppermines. Overall not the normal execution expected from Intel, but given the situation, it was pretty good.

AMD manufacturing is not as conservative as Intel. With the backs to the wall, they have taken major gambles which did not execute smoothly and caused the financial disasters of 98 and H1 99. However in H2 99 , the gambles have paid off.
