Decomposition of sf6 gas in an RF Plasma Environment

gaz sf6 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 insulating gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η sf 6 was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygen to the reactor re-Get price

Figure 1. Effects of process parameters on the Si etch rate. When testing the effects of one parameter on the rate, the other two are kept constant. It has previously been determined that the effect of O2 on the sf6 gas plasma is a dramatic increase in the F atom concentration and a subsequent decrease in lateral etching [5].Get price

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
