Electronic specialty gases used in wafer fabricationone The manufacturing process of silicon wafer is as follows:1. Purification: the silicon ore plus carbon plus oxygen produces 98% metallurgical grade silicon2. Chlorination: silicon plus hydrogen chloride gas to produce trichlorosilomethane or silicon tetrachloride3. Reduction: high purity polysilicon crystal was produced by adding trichloromethane and hydrogen4. Dissolve whirl: polysilicon becomes monocrystalline silicon crystal rod5. Cutting, polishing
