Abstract:
1. A method for treating a chamber and depositing a material on a substrate surface, comprising: exposing inner surfaces of a processing chamber and a substrate disposed within the processing chamber simultaneously to a treatment gas comprising a hydrogenated ligand compound during a pretreatment process, wherein the hydrogenated ligand compound has the chemical formula of HL, wherein the ligand L of the hydrogenated ligand compound is selected from the group consisting of cyclopentadienyl, alkylcyclopentadienyl, pentadienyl, pyrrolyl, isomers thereof, derivatives thereof, and combinations thereof and a coating of the hydrogenated ligand compound is formed on the inner surfaces of the processing chamber during the pretreatment process; and subsequently exposing the substrate to a first precursor gas to deposit a material on the substrate within the processing chamber during a vapor deposition process, wherein the first precursor gas comprises a first precursor having the chemical formula of ML′
