How Much Cost Reduction Will 450mm Wafers Provide
October 1, 2012
I've been digging around the Interwebs a bit trying to find out what the received wisdom is about how big a cost reduction can be expected if and when we transition to 450mm (18") wafers from today's standard of 300mm (12"). And the answers are totally all over the place. They vary from about a 30% cost reduction to a cost increase. That is, 450mm wafers may cost more per square cm than 300mm.
Here are some of the issues:
