Kash - Well said, IMHO. PB. <"It is very sad that no one at AMD or Motorola understands transistors." The copper doesn't speed up the Fets or transistors at all. It reduces the Al wire resistance and therefore allows faster speed paths due to reduced wiring delay.> AKA, RC delay. Nothing at all to do with xtor performance. <Clearly the Cu is a huge risk as it is a tough product to control and yield being in it's infancy in advanced semiconductor products.> 'nuff said. <The prudent thing to have done would be to dedicate Fab 30 to Al and 0.18 micron. We would be in production already at Fab 30 by now for the k-3's at 0.22 micron and the 0.18 micron transition could occur with some reasonable certitude at SDC and Fab 25 and Fab 30.> Seems reasonable to me. Intel isn't the only company that has forsaken Cu for .18. Some major DRAM companies are also pretty strident that Cu is not necessary at this point. <Now we will either get a home run and 1Ghz K7's by year end or HUGE LOSSES if yields zero out for the next year. Oh well, Jerry always was a gambler and he sure has rolled a BIG one.> Exactly. This is a home run swing. I'm personally glad my employer did not risk my livelihood in this manner. Cu interconnect is sexy. SOI (exotic IBM xtor architecture) is sexy, I suppose because it is not the same ol' boring MOS w/ Al interconnect. However, neither of these processes is required to deliver =>1GHz x86. IMHO. <Regards, Kash Johal.>
