Claim 8:
9. A method of forming a photoresist layer over a substrate in a vacuum chamber, comprising:
providing a metal precursor vapor into the vacuum chamber, wherein the metal precursor has a generic formula MRxLy, wherein M is a metal, R is a leaving group, L is a ligand, x is between 0 and 6, and y is between 0 and 6; and
providing a first oxidant vapor and then a second oxidant vapor into the vacuum chamber, wherein a reaction between the metal precursor vapor and the first oxidant vapor and then the second oxidant vapor results in the formation of the photoresist layer on a surface of the substrate, wherein the photoresist layer is a metal oxo containing material, and wherein a flowrate of the metal precursor vapor and the first oxidant vapor or the second oxidant vapor over a center of the substrate is different than a flowrate of the metal precursor vapor and the first oxidant vapor or the second oxidant vapor proximate to an edge of the substrate, and wherein the second oxidant vapor is different than the first oxidant vapor.
