polysilisium

Polysilisium, also known as polysilicon or polycrystalline silicon, is a form of silicon that is used in the semiconductor industry. It is produced by the chemical vapor deposition (CVD) process, where silicon tetrachloride (SiCl4) is reacted with hydrogen (H2) at high temperatures to form silicon crystals. The resulting polysilisium is a polycrystalline material, meaning it consists of many small crystals or grains.

Polysilisium is a key component in the manufacturing of integrated circuits (ICs) and solar cells. In IC manufacturing, it is used as a starting material for the creation of transistors and other semiconductor devices. The process involves depositing a thin layer of polysilisium onto a silicon wafer, which is then patterned and etched to form the desired circuit structures.

In the production of solar cells, polysilisium is used as a raw material for the manufacture of solar-grade silicon. This silicon is then purified and processed into solar cells, which convert sunlight into electricity.

Polysilisium is valued for its high purity and uniform crystal structure, which make it suitable for semiconductor applications. However, the production process can be energy-intensive and environmentally impactful, as it involves the use of hazardous chemicals and the generation of waste materials. Efforts are being made to develop more sustainable and environmentally friendly methods for polysilisium production.
