Plasma etching of Si and SiO2 in Sulfr hexafluoride–O2 mixtures: Journal of

Jun 04, 1998 · Without oxygen in the feed or Si in the reactor, no stable products could be detected. 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.Get price

Silicon Nanostructuring Using Sulfr hexafluoride/O2 Downstram Plasma Etching

Knizikevicius 16 performed a simulation of Si etching in SF 6 /O 2 plasma and found that at 27% O 2, the concentration of F atoms approaches the maximum value. From the two figures 1 and 2, one can conclude that, in our case, the decrease of the etching rate beyond 5% O 2 is not related to the decrease of F radicals concentration in the plasma.Get price

A Kinetic Model for Plasma Etching Silicon in a sf 6/O2 RF

The results show that as the oxygen fraction increases in a sf6 gas/O2 plasma, the number of high-energy electrons in the tail of the electron distribution and the mean electron energy both increase significantly while the plasma is kept at the same reduced electric field E/N.
