  • Oxidation of sulfur hexafluoride - ScienceDirect

    Because exploding metals react chemically with both SF6 and Oz, it becomes necessary to explode extremely small metal masses, if one wishes to study only SF6-O2 reactions. Ideally, if the metal/SF6 ratio is _sufficiently low, the explosion of the metal serves only to transfer energy from the storage capacitors to the 1. H. L.

  • High-aspect-ratio deep Si etching in SF6/O2 plasma. II

    2021-2-12In this article, the authors focus on the profiles formed by high-aspect-ratio deep Si etching with SF6/O2 plasma mixtures. One of the most serious problems for deep Si etching processes is lateral etching in the upper regions of sidewalls. This lateral etching seems to depend on time (or etched depth) rather than aspect ratio
