GE tried develop synthetic processes starting 1953. There was slow development but in 1987 Fujitsu Team quickened the process in plasma by discontinuous plasma quenching with a a stream of disassociated h2.
The microwave plasma was much faster than the dc and at 800 to 1300 F
this agrees with H2 assisting the fusing of methane gas Carbon onto the
wafer.
A method for vapor deposition of diamond by effecting an arc discharge while feeding a discharge gas between an anode and a cathode of a thermal plasma chemical vapor deposition device, radicalizing a gaseous carbon compound by feeding the gaseous carbon compound into a generated plasma jet, and permitting the radicalized plasma jet to impinge on a substrate to be treated, whereby a film of diamond is formed on the substrate.
