Abstract:
Embodiments of the present invention generally relate to an apparatus and method for uniform sputter depositing of materials into the bottom and sidewalls of high aspect ratio features on a substrate. In one embodiment, a sputter deposition system includes a collimator that has apertures having aspect ratios that decrease from a central region of the collimator to a peripheral region of the collimator. In one embodiment, the collimator is coupled to a grounded shield via a bracket member that includes a combination of internally and externally threaded fasteners. In another embodiment, the collimator is integrally attached to a grounded shield. In one embodiment, a method of sputter depositing material includes pulsing the bias on the substrate support between high and low values.

Abstract:
Disclosed are method and apparatus for treating a substrate. The apparatus is a dual-function process chamber that may perform both a material process and a thermal process on a substrate. The chamber has an annular radiant source disposed between a processing location and a transportation location of the chamber. Lift pins have length sufficient to maintain the substrate at the processing location while the substrate support is lowered below the radiant source plane to afford radiant heating of the substrate. A method of processing a substrate having apertures formed in a first surface thereof includes depositing material on the first surface in the apertures and reflowing the material by heating a second surface of the substrate opposite the first surface. A second material can then be deposited, filling the apertures partly or completely. Alternately, a cyclical deposition/reflow process may be performed.
Abstract:
Embodiments of the present disclosure generally relate to a pedestal for increasing temperature uniformity in a substrate supported thereon. The pedestal comprises a body having a heater embedded therein. The body comprises a patterned surface that includes a first region having a first plurality of posts extending from a base surface of the body at a first height, and a second region surrounding the central region having a second plurality of posts extending from the base surface at a second height that is greater than the first height, wherein an upper surface of each of the first plurality of posts and the second plurality of posts are substantially coplanar and define a substrate receiving surface.
Abstract:
Embodiments of the present disclosure are directed towards a protective multilayer coating for process chamber components exposed to temperatures from about 20°C to about 300°C during use of the process chamber. The protective multilayer coating comprises a bond layer and a top layer, the bond layer is formed on a chamber component to reduce the stress between the top layer and the chamber component. The reduced stress decreases or prevents particle shedding from the top layer of the multilayer coating during and after use of the process chamber. The bond layer comprises titanium, titanium nitride, aluminum, or combinations thereof, and the top layer comprises tungsten nitride.
