RE: <As I mentioned in an earlier post, I have come to precisely the opposite conclusion. [About performance increase from 0.25u to 0.18u] Waiting for the process guys to comment...... Chuck>

First order transistor performance is porportional to (Vin-Vt)*W/(Tox*Leff) if I remember correctly. At 1.6V I expect that Tox is already at or very near 0.18u value. If VCC at 0.18u is 1.5V then Vin-Vt is almost unchanged. Leff may come down a little but not much because the transistors were already so advanced at 0.25u. But W comes down to 0.18/0.25 = 0.72 which is the biggest change and it is in the numerator.

Process guys??????????
