Chemical vapor deposition (CVD) is a chemical process used to produce high quality, high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.ost modern CVD is either LPCVD or UHVCVD. 1  Classified by physical characteristics of vapor: 2  Aerosol assisted CVD (AACVD) â CVD in which the precursors are transported to the substrate by means of a liquid/gas aerosol, which can be generated ultrasonically.
