Just to be clear on something about the technology...
Diamond as a semiconductor almost certainly requires carbon-vapor deposition (CVD) on silicon or some other substrate. There seems to be a notion floating around that sizable diamonds can be sliced into little wafers, then have circuitry photo-etched on them. Not necessarily an impossible approach but one I think is wildly primitive and impractical. (But correct me if I'm wrong.)
At the moment Magnatek is, I am certain, all about mass-production of sizable industrial-quality diamond crystals, and perhaps even higher-quality, in bulk, for whatever purposes we or our future customers can think of.
