vapor phase etch selectivity is strongly dependent on wafer temperature [1, 2], vapor pressure [3], and moisture content [4]. In this work, we present etch selectivity dependence on the chemistry of the reactants during HFV processing. Shown in Fig. 1 are several applications for HFV processing: 1)pre-gate oxidation Hydrogen Sulfide Formula. Dihydrogen sulfide Sewer gas Sulfane Sulfurated hydrogen Sulfureted hydrogen Sulfuretted hydrogen Sulfur hydride Hydrosulfuric acidH2S may refer to:Hydrogen sulfide is produced in small amounts by some cells of the mammalian body and has a number of biological signaling functions.

The first precursor is typically a high vapor pressure metal-organic such as trimethylaluminum (TMA). It is introduced to the solid surface and adsorbs to the surface by reacting with a certain functional group, such as a hydroxyl group. The precursor will adsorb on all exposed reaction sites including sites in holes, pores, trenches, etc. on the
