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

Plasma etching of Si and SiO2 in sf 6–O2 mixtures: Journal of

Jun 04, 1998 · With an SF 6 ‐O 2 mixture in the absence of silicon, the final reaction products are F 2, SOF 4, and SO 2 F 2. The product distribution was unaffected by small SiO 2 substrates. When Si is etched, SiF 4 is the only stable silicon‐containing etch product and SOF 2 is formed in oxygen‐poor mixtures. Rapid etch rates (≳10 4 Å/min for Si) can be obtained with a high selectivity in favor of silicon (Si:SiO 2 ≳40:1); thus SF 6 ‐O 2 mixtures may represent an attractive alternative toGet price
