Yousef:

I am no expert on device here. Perhaps you can explain to me why the shorter gate length (not the gate width) is so important in determine the speed. It seems to me that the only thing that matter is the drive current. If you can hit the drive current of about 600uA-700uA
on the n-channel it is about as good as you can get and it is the drive current that determine the speed of chip isn't it?

I do like the anchor tungsten process from Intel alot. It reduces contact resistance and capacitance. If AMD chip is indeed limited by the backend then this process would help them alot in terms of reducing capacitance and resistance. On the nitride spacer you seem to point the opposite. Nitride likes to trap carriers in the film. Thus nitride space near the gate oxide would tend to increase HCI rather than improving it. I will try to ask my friend why AMD process is built the way they are.

Thanks for the information
