ted - <I have another question re the taiwan earthquake. If the power is down, does that mean that all the wafers in fabrication are lost?> The ones in process (tools running) are at significant risk. Anything in a diffusion furnace is most likely toast. These are batch process tools. Most Etch and Thinfilm tools these days are single wafer process chamber (although some tools have multiple chambers), so this mitigates the risk to wafers in process on these tools significantly, from 1 to a few wafers per lot. I will also comment that every fab I've been associated with that experienced an earthquake subsequently came up with only minor problems. However, I have only experienced 6.x magnitude earthquakes. I believe Intel survived the '89 bay area quake "OK", but I wasn't working at Intel at the time. PB
