Machining of Silicon CarbideProcess Applications and Types
Typically Silicon Carbide is produced using the Acheson process which involves heating silica sand and carbon to high temperatures in an Acheson graphite resistance furnace. It can be formed as a fine powder or a bonded mass that must be crushed and milled before it can be used as a powder feedstock.

Chemical Vapor DepositionSilicon Valley Microelectronics
Chemical vapor deposition (CVD) oxide is a linear growth process where a precursor gas deposits a thin film onto a wafer in a reactor. The growth process is low temperature and has a much higher growth rate when compared to thermal oxide. It also produces much thinner silicon dioxide layers because the film is deposted rather than grown.
