Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Precision plasma etching of Si, Ge, and Ge:P by Sulfr hexafluoride with added O2

Mar 31, 2014 · The impact of the O 2 content in SF 6 -O 2 gas mixtures on the etch rate and sidewall profile of silicon (Si), germanium (Ge), and phosphorous doped germanium (Ge:P) in reactive ion etching has been studied. The characteristics of etch rate and sidewall profile are greatly affected by the O 2 content. Below 50% of O 2 content, a large variation in Ge etch rates is found compared to that of Si, but for O 2 content above 50% the etch rates follow relatively the same trend.Get price

Sf6 Gas Processing Equipments - Vacuum Plant Instruments

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. SF 6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.Get price

Cezar Gaman - Post-Doctoral Researcher - Dublin City

The dissociation fraction in Sulfr hexafluoride/Ar (95/5%) plasma at 20 mTorr was over a factor of 22 lower than gaz sf6/O2/Ar (85/10/5%) plasma. For a fixed gas pressure and power of 60 mTorr and 500 W the F+ signal showed a variation of up to a factor of 60 depending if O2 was in the feedstock gas which indicates a marked enhancement of [F] with O2 addition.Get price
