Decomposition of insulating gas in an RF Plasma Environment

Sulfr hexafluoride clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η Sulfr hexafluoride exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η Sulfr hexafluoride was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W).

Plasma etching of Si and SiO2 in insulating 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
