Yousef: The AMD engineer told me the K6 polygate length (in your terminology) on their 0.35um process is 0.29um-0.30um. I asked him how come AMD doesn't go for smaller size to get higher speed. He said the transistor was initially designed for gate of 0.31um. Thus they pushed it down as hard as they could. To match Intel's gate length they would have to redesign the transistor all over. It is not a good idea since they are under great pressure to come up with the K6+ and K7 and making money on the K6 at the same time. Intel's nitride spacer looks very good. I read in literature that nitride spacer becomes more important as you drop the polygate length below 0.18um. The reason is that as the poly length gets smaller you need higher temperature to form TiSi. However, Ti will react with the SiO2 spacer to form TiSi and you get bridging whereas nitride is less likely to react with Ti. How small of the polygate length you can go down to with TiSi? What is Intel's 0.25um process poly CD? Thanks for the information Maxwell
