Re. "Some minor circuit modifications and process improvements in the poly gate etching have corrected the original speed problem and Intel will have no problem making 600 and 667 MHz Coppermines - in the not-too-distant future."

Based on Intel's published comparisons between their .25um 1.8V and .18um 1.5v device designs(Ion / Ioff and other performance metrics),I would expect at least a 20% to perhaps 25% improvement in COPPERMINE. So if 600Mhzz is the last speed sort without significant circuit limited yield loss at .25um 1.8v, you might conclude that INTEL will eventually go to perhaps 750Mhz with COPPERMINE. This seems to agree with their roadmap and makes sense to me. Also, 67Mhz probably represents only about 90A in channel length. MAYBE the delay was just a foul up in targeting the correct channel length. Foul ups tend to be easier to fix than REAL problems,
