Haven't they moved up to 12"/300mm wafers yet?
I haven't been able to find any current pricing, the only reference to 12" wafer pricing I could find was from 2003; and at that time they cost about $200USD, and 8" were $30-40USD. 12" were relatively new at that point, and I would assume (perhaps incorrectly) that the cost per in^2 of 8" vs. 12" has since reversed. Although I'm sure actual prices have gone way up. The feature widths back in 2003 were 2-4x the sizes used today, so probably needed less perfect wafers.
I had always been under the impression that the cost of the actual silicon though, while not trivial, was a relatively small part of the equation. It's the $1B+ that a fab costs, along with labor, litho equipment, masks, design/engineering, etc. that truly set the cost to get a good die out the door. And the fact that a fab is basically a fixed capacity manufacturing facility, only compounds that. You can't just move faster to increase output, you have to increase yield to have any gains.
