Patent ID: 8071452

Claim:
A method for depositing a film on a substrate that is within a reaction chamber, the method comprising applying an atomic layer deposition cycle to the substrate, the cycle comprising: exposing the substrate to a first precursor gas pulse sequence, wherein the first precursor gas sequence includes: exposing the substrate to a first precursor gas for a first precursor pulse interval then removing the first precursor gas thereafter; and exposing the substrate to a first oxidant gas for a first oxidation pulse interval then removing the first oxidation gas thereafter; exposing the substrate to a second precursor gas pulse sequence, wherein the second sequence includes: exposing the substrate to a second precursor gas for a second precursor pulse interval then removing the second precursor gas thereafter; and exposing the substrate to a second oxidant gas for a second oxidation pulse interval then removing the second oxidation gas thereafter; wherein the first precursor gas comprises at least one of tetrakis-ethyl-methylamino hafnium (TEMAHf) and lanthanum tris-formamidinate (LaFAMD) 3 .
