SiH4 is used in the manufacturing process of semiconductors, TFT-LCD and thin film solar cells. This is used to deposit silicon on wafer in semiconductors and to deposit silicon on TFT(thin film transistor) on top of glass substrate for TFT-LCD.This gas in expected to show increased demand with NF3 gas, following continued expansion of semiconductor, TFT-LCD and thin film sola cell lines.
