High purity silane
WebAfterwards, the high purity silane that is obtained is introduced into a vapor deposition reactor where it disintegrates to produce the Si SG. The Union Carbide Co. process achieves higher efficiencies since the conversion of silane in silicon is greater than the trichlorosilane to silicon transformation used in the Siemens process. WebJan 1, 2014 · High-Purity Polycrystalline Silicon The production processes are well-known and have been in use by the major polysilicon suppliers in the United States, Japan, and Europe since the 1950s. These plants are continuing capacity expansions, and new plants have been built in Japan, China, Taiwan, Korea, Europe, and Ukraine.
