Semiconductor business usage scenarios: Polysilicon is really a silicon materials composed of many small grains, that is widely used in built-in circuits, solar cells and also other fields. Chemical vapor deposition (CVD) has become the key techniques to put together polycrystalline silicon. The basic basic principle would be that the silicon source fuel, such as SiH4, is decomposed at high temperature and deposited over the substrate to sort polycrystalline silicon： SiHCl3 + H2 ⇒ Si + 3HCl Beneath large temperature and vacuum circumstances, the silicon resource gasoline was fed into the chemical vapor deposition. Polycrystalline silicon is at last received.The Semiconductor Grade Quartz Bell Jar is a crucial Portion of the polycrystalline silicon CVD reactor. Polycrystalline silicon CVD reactor
