Maxwell, Re: "I talked to an AMD engineer who has dissected the PII chip ..." Very good information, Maxwell ... you have a very good contact there at AMD. Yes, Intel does use Nitride spacers ... but, I am very surprised that AMD does not. You see, Nitride spacers give better Hot Carrier Injection (HCI) resistance and better control of Short Channel Effects (SCE). This could be one reason the FET's at AMD are lower performing. Also I can tell that you have real info here because Intel does etch their contact very hard and they tend to form "anchors" with the tungsten plugs "seated" well down into the Aluminum (through the Ti/TiN layer). This does give very good low resistance contacts and the overetch insures that the contact yield is high. I don't expect this to play a significant role in performance. BTW, does your friend see any difference in the physical gate length. I would expect this to be shorter on the PII material (as compared to AMD). Good to hear from you, Maxwell. Make It So, Yousef
