Silicon carbide (SiC ) thin film have been prepared on both Si (100 ) and SiO patterned Si2 (100 ) substrates by the high vacuum metalorganic chemical vapor deposition (MOCVD ) method using a single source precursor at various growth temperatures in the range of 700–1000 8C. Diethylmethylsilane (DEMS ) was used as precursor without carrier gas.
Chemical vapor deposition works well in the production of cubic silicon carbide. Unfortunately, however, the process is very expensive, so interested parties would do well to avoid this method unless absolutely necessary.

Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, highperformance, solid materials. The process is often used in the semiconductor industry to produce thin films.. In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit.
