Patent ID: 8027746

Claim:
A method of depositing a material layer on a substrate comprising: (a) positioning a substrate on a wafer support in a deposition chamber comprising a first deposition region and a second deposition region, wherein the first and second deposition regions are integrally connected to one another, and wherein the wafer support is movable between the first and second deposition regions; (b) pulsing a first deposition gas into the first deposition region and pulsing a second deposition gas into the second deposition region; (c) moving the wafer support with the substrate thereon into the first deposition region wherein a first monolayer of the first deposition gas is chemisorbed onto the surface of the substrate; (d) moving the wafer support with the substrate thereon into the second deposition region wherein a first monolayer of the second deposition gas is chemisorbed on the first monolayer of the first deposition gas; and (e) repeating steps (c) and (d) until a material layer having a desired thickness is achieved.
