Plasma etching of Si and SiO2 in sf 6–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
