Abstract
A processing chamber with a flow-restricting ring is generally provided. In one embodiment, a processing chamber includes a chamber body, a lid assembly, a substrate support and a flow-restricting ring. The chamber body has sidewalls and a bottom. The lid assembly is disposed on the sidewalls and encloses an interior volume of the chamber body. The substrate support is disposed in the interior volume of the chamber body and is adjustable in elevation between the lid assembly and the bottom of the chamber body. The flow-restricting ring has an outer edge disposed proximate the sidewalls of the chamber body and an inner edge disposed proximate the substrate support when the substrate support is disposed in an elevated position. The inner edge of the ring and the substrate support are disposed in a spaced-apart relation defining an annular flow control orifice. The flow control orifice disposed proximate the substrate support enhances flow uniformity across the diameter of a substrate seated on the substrate support during processing.
