Decomposition of gaz sf6 in an RF plasma environment

The decomposition fraction of insulating gas [etasf6 gas (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/gaz sf6 ratio in an SiO2 reactor. The species detected in both insulating gas/Ar and sf6 gas/O2/ Ar RF plasmas were SiF4, SO2, Fe2, SO2F2, SOF2, SOF4, S2F10, S2OF10, S2O2F10, and SF4.Get price

Decomposition of Sulfr hexafluoride and H2S Mixture in Radio Frequency

May 28, 2003 · Sulfur hexafluoride (sf6 gas) is a gaseous pollutant generated in manufacturing processes in the semiconductor industry. Hydrogen sulfide (H2S), as a reductant, was used to treat gaz sf6 in a radio frequency (RF) plasma system. In the insulating gas/Ar plasma system, SiF4 and SO2 were the two dominant species detected in the glass reactor; other detected species were SO2F2, SOF2, and SOF4.
