Decomposition of Sulfr hexafluoride in an RF plasma environment.

Shih M, Lee WJ, Tsai CH, Tsai PJ, Chen CY. Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of Sulfr hexafluoride. The decomposition fraction of Sulfr hexafluoride [etasf 6 (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/Sulfr hexafluoride ratio in an SiO2 reactor.Get price
