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. In typical CVD, the wafer (substrate) is exposed to one or more volatile precursors, which react and/or decompose on the.
AVS has built CVD furnace for the chemical vapor deposition (CVD) and chemical vapor infiltration (CVI) of a variety of materials, including silicon carbide, pyrolytic carbon, boron nitride, zinc selenide and zinc sulfide. AVS gas and vapor delivery systems coordinate mass flow controls and modulating valves to deliver.
