Abstract:
1. A process for depositing a bismuth-containing oxide thin film on a substrate in a reaction space by atomic layer deposition, comprising alternately and sequentially contacting the substrate with a first metal reactant and a second oxygen source, wherein the first metal reactant is an organic bismuth compound having at least one monodentate alkoxide ligand and one bismuth atom, wherein the organic bismuth compound is tris(2,3-dimethyl-2-butoxy)bismuth(III), and wherein the oxygen source is selected from the group consisting of water, oxygen, hydrogen peroxide, aqueous solutions of hydrogen peroxide, ozone, oxides of nitrogen, halide-oxygen compounds, peracids (—O—O—H), alcohols, oxygen-containing radicals, oxygen-containing plasma and mixtures thereof.
