Claim 0:
1. A method of forming a photoresist layer over a substrate, comprising:
forming a first metal oxo film on the substrate with a first vapor phase process including a first metal precursor vapor and a first oxidant vapor, wherein a flowrate of the first metal precursor vapor and the first oxidant vapor is non-uniform across a surface of the substrate; and
forming a second metal oxo film over the first metal oxo film with a second vapor phase process including a second metal precursor vapor and a second oxidant vapor, wherein a flowrate of the second metal precursor vapor and the second oxidant vapor is non-uniform across the surface of the substrate, and wherein the second oxidant vapor is different than the first oxidant vapor.
