Abstract:
Apparatus and methods of measuring and controlling the gap between a susceptor assembly and a gas distribution assembly are described. Apparatus and methods for positional control and temperature control for wafer transfer purposes are also described.
Abstract:
Described are apparatus and methods for processing a semiconductor wafer in which the gap between the wafer surface and the gas distribution assembly remains uniform and of known thickness. The wafer is positioned within a susceptor assembly and the assembly is lifted toward the gas distribution assembly using actuators. The wafer can be lifted toward the gas distribution assembly by creating a fluid bearing below and/or above the wafer.
Abstract:
A substrate processing chamber and methods for processing multiple substrates is provided and generally includes a plurality of spaced gas distribution assemblies and a substrate support apparatus to rotate substrates along a path adjacent each of the plurality of gas distribution assemblies. Each of the gas distribution assemblies comprises a plurality of elongate gas ports extending in a direction substantially perpendicularly to the path traversed by the substrate.
Abstract:
Provided are atomic layer deposition apparatus and methods including multiple gas distribution plates including stages for moving substrates between the gas distribution plates.

Abstract:
In a first aspect, an apparatus for cleaning a thin disk is provided. The apparatus includes a support roller for supporting a rotating wafer within a wafer cleaner. The support roller comprises a guide portion, for receiving an edge of a wafer, having an inclined surface comprising a low-friction material and adapted to allow the wafer edge to slide thereagainst; and an edge-trap portion for retaining the edge of the wafer and having a transverse surface comprising a high-friction material and adapted, when in communication with the edge of the wafer, to resist sliding thereagainst. Numerous other aspects are provided.
Abstract:
Embodiments of the invention relate to apparatus and methods for depositing materials on substrates during atomic layer deposition processes. In one embodiment, a chamber lid assembly comprises a channel having an upper portion and a lower portion, wherein the channel extends along a central axis, a housing having an inner region and at least partially defining two or more annular channels, an insert disposed in the inner region and defining the upper portion, the upper portion fluidly coupled with the two or more annular channels, and a tapered bottom surface extending from the bottom portion of the channel to a peripheral portion of the chamber lid assembly.
Abstract:
Embodiments of the present invention relates to an apparatus and method for cleaning a substrate using scrubber brushes. One embodiment of the present invention provides a substrate cleaner comprises two scrubber brush assemblies movably disposed in a processing volume. The two scrubber brush assemblies are configured to contact and clean opposite surfaces of a substrate disposed in the processing volume. The substrate cleaner also comprises a positioning assembly configured to simultaneously adjust positions of the two scrubber brush assemblies, wherein the positioning assembly makes substantially the same amount of adjustment to the first and second scrubber brush assemblies in mirror symmetry.
Abstract:
In a first aspect, a method of cleaning an edge of a wafer is provided. The method comprises providing an edge cleaning roller having a first inclined frictional surface for cleaning an edge corner of a wafer rotating within a first plane; and causing the edge cleaning roller to rotate within a second plane at an angle to the first plane while the inclined frictional surface contacts and cleans the edge corner. Numerous other aspects are provided.
Abstract:
In a first aspect, an apparatus is provided for forming a scrubber brush assembly. The apparatus includes a mandrel adapted to be inserted into a scrubber brush so as to form a scrubber brush assembly, the mandrel having: a first end; a second end; and one or more position guides adjacent at least one of the first and second ends and adapted to position a scrubber brush on the mandrel. Numerous other aspects are provided.
