Plasma etching of Si and SiO2 in insulating gas–O2 mixtures: Journal of

Jun 04, 1998 · The products of reaction and etch rates of Si and SiO 2 in SF 6 ‐O 2 plasmas have been studied as a function of feed composition in an alumina tube reactor at 27 mHz, 45 W, and 1 Torr. There is a broad chemical analogy with CF 4 ‐0 2 plasmas. As in CF 4 ‐0 2 mixtures, the rate of Si etching and 703.7‐nm emission from electronically excited F atoms each exhibit distinct maxima as a function of feed gas composition; these data support a model in which fluorine atoms, the etchingGet price

In this experiment, the highest EY of the no O 2 group occurred when the concentration of SF 6 was 6%, which was 25.16 g kW −1 h −1; the highest EY of the oxygen-containing group appeared under the condition of 10% SF 6 and 2% O 2, which was 37.99 g kW −1 h −1. The maximum EY increased by 50.99%.Get price

Decomposition of Sulfr hexafluoride in an RF Plasma Environment

sf6 gas 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 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-Get price

Decomposition of Sulfr hexafluoride in an RF plasma environment.

Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of insulating gas. The decomposition fraction of sf 6 [etasf 6 (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/gaz sf6 ratio in an SiO2 reactor.Get price
