Effect of the addition of SF6 and N2 in inductively

The best results were obtained between 15 sccm and 25 sccm of SF 6 with an etch rate of 53 nm min −1. Mass spectrometry measurements have confirmed the increase in the chlorine radicals'' density into the gas mixture. However, the observation of the etched surface clearly showed that the value of 15 sccm is the optimal value for SF 6 mass flow.

or several times smaller than that of SF6. In the present paper, insulation characteristics were experimentally obtained while varying the mixture ratio under a quasi-uniform electric field assuming GIS. Consequently, compared to the GWP of pure SF6, the GWP was about 12% to 38% for gas mixtures with C3F8/N2 or C3F8/CO2 and 18% to 70% for gas
