Pure CVD silicon carbide wafer carriers | Engineer Live
The pure CVD SiC wafer carriers significantly outperform traditional wafer carriers used in this process, which are graphite and coated with a layer of CVD SiC. These coated graphite-based carriers cannot withstand the high temperatures (1100 to 1200 degrees C) required in GaN deposition for today’s high brightness blue and white LEDs.

CVD Graphene - Creating Graphene Via Chemical Vapour …
CVD graphene is created in two steps, the precursor pyrolysis of a material to form carbon, and the formation of the carbon structure of graphene using the disassociated carbon atoms. The first stage, the pyrolysis to disassociated carbon atoms, must be carried out on the surface of the substrate to prevent the precipitation of carbon clusters (soot) during the gas phase.
