Silicon is one of the most extensively used elements in the world. It is dark gray and semi-metallic with a bluish tinge. It has a melting point of 1,410°C, a density of 2.32 g/cc, and a vapor pressure of 10-4 Torr at 1,337°C. It is a brittle metalloid which can chip easily. Silicon is a semiconductor which is heavily utilized in the electronics and computer industries. It is often doped with arsenic, phosphorus, or boron depending on the application. It is evaporated under vacuum for circuit device, data storage device, and battery fabrication.

Vacuum evaporation means the evaporation materials are evaporated to atoms or molecules in vacuum by current heating, electron beam heating and laser heating. Atoms or molecules make rectilinear motion to impact substrate surface and condense to form films.
