Decomposition of Sulfr hexafluoride 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 sf 6 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 sf6 gas–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
