Hugh, I suspect Intel is quietly at work on these processes. The SOI has long been used with sapphire and diamond as the insulating substrate in many military ICs allowing high speed, rad hard and other attributes to be acquired.
I wonder if the new plasma deposited diamond films are the base for this technique. Diamond polycrystalline films can now be deposited on may substrates from plasma and have higher thermal conductivity. This conductivity is however, anisotropic and requires a certain axial orientation of the diamond to optimize this. Whether or not thermal conduction will be extremely high with polycrystalline diamond I do not know? Perhaps it will be good enough and it is an insulator if so desired. Perhaps the tech will know these answers?

For high end chips the cost can be justified.

Bill
