Polysilicon, short for polycrystalline silicon, is a material widely used in the semiconductor industry for various electronic applications. It is produced by depositing a layer of silicon using chemical vapor deposition (CVD) techniques.
Polysilicon is composed of multiple small silicon crystal grains, giving it a polycrystalline structure. This material possesses excellent electrical conductivity, making it suitable for fabricating integrated circuits, solar cells, and other electronic components. Polysilicon’s properties can be further enhanced by doping it with specific impurities to control its electrical characteristics. Its high melting point, low thermal expansion, and compatibility with silicon-based processes make polysilicon an essential material in the manufacturing of advanced electronics.
