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

Oxidation of sulfur hexafluoride - ScienceDirect

Extremely efficient conversion of electrical to chemical energy is obtained when small metal masses are exploded in these gaseous mixtures. The predominant product is always SOF 2, but minor amounts of SOF 4, SO 2 F 2, SO 2 and SF 6 form to different extents when reaction parameters are varied. SF 5 Cl O 2 reactions are also fast by comparison to SF 6 oxidation, and the predominant product of SF 5 Cl oxidation initiated by metal explosions is likewise SOF 2.Get price

Then, etching products, such as SiS, CS, SiF x, and CF x (x = 1–4) molecules, are generated and evaporated. In particular, SiF x is the main generated species, and Si atoms are more likely to vaporize than C atoms. The remaining C atoms on SiC generate C–C bonds that may decrease the etching rate.Get price
