    摘要: Apparatus for improving temperature uniformity across a substrate are provided herein. In some embodiments, a deposition ring for use in a substrate processing system to process a substrate may include an annular body having a first surface, an opposing second surface, and a central opening passing through the first and second surfaces, wherein the second surface is configured to be disposed over a substrate support having a support surface to support a substrate having a given width, and wherein the opening is sized to expose a predominant portion of the support surface; and wherein the first surface includes at least one reflective portion configured to reflect heat energy toward a central axis of the annular body, wherein the at least one reflective portion has a surface area that is about 5 to about 50 percent of a total surface area of the first surface.
