Description

Technical Field

[0002] Polysilicon is a polycrystalline semiconductor material used to make electronic parts and components. It can be used in technically demanding environments. It is a polycrystalline semiconductor material composed of multiple crystals. After special treatment, it can show higher electrical parameters, lower noise characteristics and higher thermal tolerance. Polysilicon is a form of single-element silicon. When molten single-element silicon solidifies under supercooling conditions, silicon atoms are arranged into many crystal nuclei in the form of diamond lattices. If these crystal nuclei grow into grains with different crystal plane orientations, these grains will combine and crystallize into polysilicon. Polysilicon material is the direct raw material for the production of single-crystal silicon. It is the basic electronic information material for contemporary semiconductor devices such as artificial intelligence, automatic control, information processing, and photoelectric conversion.
