post 3 The major reason to move to 300mm is to increase the amount of chips you can produce and lower the cost of production....if we already have over capacity with the current 200mm tool base, I highly doubt that 300mm will solve the supply problem....it will just add another 2x more to the supply. And basically the prices will go down to the current margin levels. Kinda like the move by DRAM makers from 4M to 16M to 64M...4M was a bonanza because there was huge demand and not enough supply, boy did the DRAM guys make money, I'm sure you all remember MU. As more 4M supply came online and margins disappeared, folks started to migrate to 16M at 200mm and .5/.35u....cause that's where all the profits were, so the whole herd moved towards 16M. As the margins dried up there...everyone moved to 64M .35/.3u. And guess what, there are no profits to be had at 64Ms. For current needs, 64M chips are more than enough.....so I doubt that we will see any big move to 128M. My point here is that....everyone moves to areas of profit and saturates them...this cannot continue forever, and I think they will realize this sooner or later. supply has to be cut or demand has to skyrocket to meet supply. At this point we have alot of noise about applications that will require tons of memory and horsepower, but its not being used yet and no one has predictions as to when it will be needed. The $1,000 PC's, who's sales are growing the fastest are 166 to 200Mhz PC's, it seems that that is plenty of power to run todays apps. The migration to 300mm will happen, but the pace and timing is the question, I suspect that it will be after 2000 before we start to see any significant move toward 300mm. And as we get closer to the point of transition, I suspect we will see a slowing of Cap spending as they absorb their 200mm capacity before they jump to 300mm. dave
