I had heard there was an "intermediate" wafer size between 300 and 450mm which is more cost effective from an equipment and infrastructure point of view. It would still provide a path for reduced $$/mm2 and in a more manageable way. Comments from the equipment industry?
C'mon guys? How many people think the wafer size is unlimited. What's next? A 1 meter wafer?!?
I predict Dr. Moore's Law will soon continue along other tracks than wafer size. You heard it here first! :)
It will be interesting to see the responses we get from our 5th annual process technology survey (currently underway at http://www.wwk.com/2011survey.pdf). The responses from the previous 4 surveys on 450mm manufacturing indicated more than 6 years out (39% responded never), more than 6 years out (56% responded never), beyond 2015(17% responded never), and beyond 2017(38% responded never).
