US Classification:

216 67, 216 79, 134 11, 134 221

Abstract:

Methods of using reactive gases containing a perfluoroketone having 4 to 7 carbon atoms for removing unwanted deposits that build up in a vapor reactor, for etching dielectric and metallic materials in a vapor reactor, and for doping a material in a vapor reactor are described.
