Abstract:
1. An atomic layer deposition method, comprising: providing a semiconductor substrate within a deposition chamber; flowing a first metal halide-comprising precursor gas to the substrate within the chamber under conditions which form a first monolayer on the substrate, the first monolayer comprising metal and halogen of the metal halide of the first metal halide-comprising precursor gas, the first metal halide-comprising precursor gas and the H while flowing the first metal halide-comprising precursor gas to the substrate within the chamber, flowing H flowing a second precursor gas to the first monolayer under conditions which react with the first monolayer and form a second monolayer on the substrate, the second monolayer comprising the metal; and repeating at least some of the flowing of the first metal halide-comprising precursor gas, at least some of the flowing of the H
