Patent ID: 8153535

Claim:
A method comprising: a. providing a showerhead, wherein the showerhead comprises four segments; b. designating four regions on a surface of a substrate; c. depositing a first material on a first region of the surface of the substrate, wherein the depositing of the first material comprises; c1. providing a first precursor to a first region of the surface of the substrate; d. depositing a second material on a second region of the surface of the substrate, wherein the depositing of the second material comprises; d1. providing a second precursor to a second region of the surface of the substrate; e. depositing the first material on a third region of the surface of the substrate, wherein the depositing of the first material comprises; e1. providing a first precursor to a third region of the surface of the substrate; f. depositing the second material on a fourth region of the surface of the substrate, wherein the depositing of the second material comprises; f1. providing a second precursor to a fourth region of the surface of the substrate; g. providing a first plasma gas to each of the first and third segments of the showerhead, h. providing a first plasma to each of the first and third segments of the showerhead, i. providing the first plasma to each of the first and third regions of the surface of the substrate, j. providing a second plasma gas to each of the second and fourth segments of the showerhead, k. providing a second plasma to each of the second and fourth segments of the showerhead, l. providing the second plasma to each of the second and fourth regions of the surface of the substrate, m. repeating steps c through l until desired thicknesses of the first material and second material are reached.
