摘要: A method and apparatus for atomic layer deposition (ALD) is described. In one embodiment, an apparatus comprises a vacuum chamber body having a contiguous internal volume comprised of a first deposition region spaced-apart from a second deposition region, the chamber body having a feature operable to minimize intermixing of gases between the first and the second deposition regions, a first gas port formed in the chamber body and positioned to pulse gas preferentially to the first deposition region to enable a first deposition process to be performed in the first deposition region, and a second gas port formed in the chamber body and positioned to pulse gas preferentially to the second deposition region to enable a second deposition process to be performed in the second deposition region is provided.
