Excerpt
Introduction: In three earlier papers In this series we synthesized, evaluated, and extended the available information on electron collision processes with CF, CHF3, and CC12F2. We have continued this effort to provide the most accurate information available on the electronic interactions of gases of interest to the semiconductor industry, and in this paper we report on perfluoroethane (C2F6, hexafluoroethane). Perfluoroethane is a man-made gas with many applications. It is used in the aluminum industry, in the semiconductor industry, in plasma chemistry and etching application, in pulsed power switching gas mixture and in...
