Patent ID: 8709924

Claim:
A method of processing a substrate, comprising: (a) disposing the substrate in a process chamber; (b) providing a first precursor material to the process chamber, wherein the first precursor is a catalytic precursor selected from the group consisting of O 2 , O 3 , N 2 O, H 2 O 2 , NO, N 2 O 5 alcohols organic and inorganic peroxides carboxylic acids radical oxygen compounds, and combinations thereof; (c) reacting the first precursor material to form a layer of the first precursor on the substrate; (d) providing a second precursor material to the process chamber wherein the second precursor is a dopant precursor; (e) reacting the second precursor material with the layer of the first precursor to form a dopant layer on the substrate; (f) repeating steps (b) - (e) in sequence until the dopant layer reaches a target thickness; and (g) diffusing the dopant layer into the substrate by heating the substrate.
