Plasma etching of Si and SiO2 in sf6 gas–O2 mixtures: Journal of

Jun 04, 1998 · The products of reaction and etch rates of Si and SiO 2 in SF 6 ‐O 2 plasmas have been studied as a function of feed composition in an alumina tube reactor at 27 mHz, 45 W, and 1 Torr. There is a broad chemical analogy with CF 4 ‐0 2 plasmas. As in CF 4 ‐0 2 mixtures, the rate of Si etching and 703.7‐nm emission from electronically excited F atoms each exhibit distinct maxima as a function of feed gas composition; these data support a model in which fluorine atoms, the etchingGet price

Myth About sf6 gas Gas In Electrical Equipment

Apr 12, 2021 · This is just the UK, Sulfr hexafluoride stays in the atmosphere for a minimum 1000 years where as CO2 100 years. sf 6 is on the increase the US expect a 6.2% increase over the next 6 years. Sulfr hexafluoride might not damage the Ozone but it will accelerate Global Warming given the fact that it stays in the atmosphere longer can cause more damage over a longer period of time.Get price
