Truly amazing that they can manufacture 8" wafers with their Smart Cut© technology.

In my previous life we put epitaxial superconductor on the sapphire of a silicon on sapphire wafer. The naval research folks had fabricated CMOS devices on the Si. After we patterned a SQUID (Superconducting QUantum Interference Device) in the superconductor the wafer had both working superconducting and CMOS devices on the same (Al2O3) substrate. Useless, I might add, but proof of concept.

If I remember right the 4" SOS wafers were ~$400 apiece. I guess with the "cleaving" technology you effectively get two device surfaces instead of one surface with the old SOS technology.

Thanks for the links, Will.
