Paul, Re: SOI Thanks for the article follow-up. Now I know a little more. So, the minimum Dresden implanters required would be 5000 WPW / (7 * 24 / 1.2) = 35 for IBM's old process and probably less now given likely process advances since 1998. EDIT: Using THEWATSONYOUTH's 3-4x estimate of increased throughput would mean about 10 implanters for Dresden. Re: "Note the additional $400 to $500/wafer cost adder for SOI !!" This was a multiplier of eight for SOI (or cost adder of $340-440 but the details don't really matter). But the article indicated this multiplier would drop to "two to four times" with higher throughput equipment. Also, article noted the time required (thickness of oxide layer) falls with lower voltages of smaller process geometry. These costs per wafer would seem to be pretty modest given the potential value when applied to microprocessor production. Hm. I think this counts as all my learning for the day (goal is only at least one new thing). Off to Fry's to buy some parts to round out a new system built for/with my half-brother. -PT
