For example, consider a North America based fab producing 30,000 - 300mm wafers at 130nm for microprocessors. We calculate a wafer cost of $2,624 per wafer.

I remember paying something like $3,500 per 8" (200mm) BiCMOS wafer in the mid 1990's. Key points were 4 layers of metal (I'd use some for shielding the analog parts) and Bipolar for better analog needed for better preamps to detect photons. I think we gave up state of the art MOS line widths in exchange for the cost of Bipolar so $3,500 was a good estimate for a state of the art 200mm wafer. I was under the impression the goal of 300mm was to give about the same wafer cost where the actual cost savings comes from more net die per wafer. $2624 factory cost gives them a nice mark-up.

I wonder if there is a table anywhere showing raw wafer prices vs process, year, size, etc?
