Plasma etching of Si and SiO2 in Sulfr hexafluoride–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
