Abstract:
A valve assembly comprises a valve body having an interior valve seat and a plurality of adapter ports. A non-metallic sealing material provides a vacuum seal between mating surfaces of adjacent vacuum components, and direct physical contact between mating surfaces ensures good thermal conduction within the valve assembly.
Abstract:
Methods of seasoning a remote plasma system are described. The methods include the steps of flowing a silicon-containing precursor into a remote plasma region to deposit a silicon containing film on an interior surface of the remote plasma system. The methods reduce reactions with the seasoned walls during deposition processes, resulting in improved deposition rate, improved deposition uniformity and reduced defectivity during subsequent deposition.

Abstract:
Techniques for a door system for sealing an opening between two chambers in a semiconductor processing system are described. A sealing member seals the opening when a door is in a closed position. To selectively open and close the opening, an actuator moves the door. A valve actuator switch provides a first or second pressure to the actuator depending on the pressure inside a first chamber. In one embodiment, a sensor monitors the pressure inside the first chamber.
Abstract:
Apparatus and methods for gas distribution assemblies are provided. In one aspect, a gas distribution assembly is provided comprising an annular body comprising an annular ring having an inner annular wall, an outer wall, an upper surface, and a bottom surface, an upper recess formed into the upper surface, and a seat formed into the inner annular wall, an upper plate positioned in the upper recess, comprising a disk-shaped body having a plurality of first apertures formed therethrough, and a bottom plate positioned on the seat, comprising a disk-shaped body having a plurality of second apertures formed therethrough which align with the first apertures, and a plurality of third apertures formed between the second apertures and through the bottom plate, the bottom plate sealingly coupled to the upper plate to fluidly isolate the plurality of first and second apertures from the plurality of third apertures.

Abstract:
Embodiments of a manifold assembly are provided herein. In some embodiments, a manifold assembly includes a first manifold having a first inlet, for coupling to a high temperature fluid source, and a first outlet; a second manifold having a second inlet and a second outlet; and a connector portion coupling the first outlet of the first manifold to the second inlet of the second manifold, the connector portion includes a polymer block; and a thermal isolator disposed between the polymer block and the first manifold.
Abstract:
Embodiments of a valve assembly for a process chamber having improved seal performance are provided herein. In some embodiments, a valve assembly for a process chamber includes a housing having an opening disposed in a wall thereof and through which a substrate may be transferred; a door movably coupled to the housing in a plane substantially parallel to the wall of the housing for selectively sealing the opening; a compressible sealing member disposed at least partly between an upper surface of the door and a corresponding surface of the housing for forming a seal therebetween by compression of the compressible sealing member in a direction substantially perpendicular to the wall when the door is in a closed position; and a mechanism for restricting the exposure of the compressible sealing member to an environment on a process chamber side of the housing.
