cvd meaning in oil and gas

Chemical vapor deposition (CVD) is a chemical process often used in the semiconductor industry for the deposition of thin films of various materials. In a typical CVD process the substrate is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit. Frequently, volatile byproducts are also produced, which are removed by gas flow through the reaction chamber.<p> <p> CVD is widely used in the semiconductor industry, as part of the semiconductor device fabrication process, to deposit various films including: polycrystalline, amorphous, and epitaxial silicon, carbon fiber, filaments, carbon nanotubes, SiO2, silicon germanium, tungsten, silicon nitride, silicon oxynitride, titanium nitride, and various high-k dielectrics. The CVD process is also used to produce synthetic diamonds.<p> <p> This explaination is taken from a free encyclopedia
