Yousef, nice explanation of what typical IC manufacturing process steps are, but your comparisons of AMD/Intel are inaccurate: AMD supply voltage of 2.2V for .25um more closely matches Intel's .35um 2.5V process Sorry, Intels 0.35µ process was 2.8v, not 2.5v. The Intel 0.25µ voltage is 2.0. Last time I checked, AMD's 2.2 voltage was a lot closer to 2.0 than to 2.8! Alpha CPU from Digital (more transistors) and various RISC CPU's have used sub 2v supply voltage for years -- does this mean they are ahead of Intel in process technology? Since a process generation like .25um takes about 2-3 years to develop AMD's first full quarter of 0.35µ production was 2Q'97, when they made 450,000 K6's, mostly 166 and 200 MHz. Their first full quarter of 0.25µ production was 2Q'98, when they made 1.2M K6's and K6-2's using quarter micron, mostly at 300 MHz. That's ONE year, not 2-3. If Intel takes 2-3 years to get to 0.18µ (AMD K-7), they will be in deep doo-doo. Petz
