Abstract:
1. A method for forming a high-k film, comprising: disposing a substrate in a process chamber; and exposing the substrate to a gas pulse sequence to deposit a high-k film with a predetermined thickness, wherein the gas pulse sequence includes, in any order: a) sequentially first, exposing the substrate to a gas pulse comprising a first metal precursor, and second, exposing the substrate to a gas pulse of a first oxidation source comprising H b) sequentially first, exposing the substrate at to a gas pulse comprising a second metal precursor, and second, exposing the substrate to a gas pulse of a second oxidation source comprising oxygen radicals (O), O wherein each of a) and b) are repeated any number of times, and wherein the gas pulse sequence including a) and b) is repeated, in any order, any number of times to achieve the predetermined thickness.
