sf 6 analysis KEPCO

The etching rates and reaction products of refractory metals (W, Mo, and Ta) and silicon have been studied in a sf6-O 2 r.f. plasma at 0.2 torr. The relative concentrations of WF 6 and WOF 4 and the intensities of the WF + n (n=3−5), WOF + m (m=1−3), MoF + n, and MoF + m ions have been measured by mass spectroscopy. An analysis

  • An Ultra-Trace Analysis Technique for SF 6 Using Gas

    Abstract. Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations.This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 s high detection sensitivity also facilitates greater usage efficiency
