Decomposition of gaz sf6 in an RF Plasma Environment

sf6 gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η sf6 gas 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-duced the electron density and, thus, reduced the dis-sociation of SF 6 and inhibited the production of free radicals.Get price
