Patent number: 9570328Abstract: Apparatus for use with multi-zonal heating sources are provided. In some embodiments, a substrate support may have a pocket disposed in a surface of the substrate support and a lip disposed about the pocket to receive an edge of a substrate and to support the substrate over the pocket such that a gap is defined between a pocket surface and a backside surface of the substrate when the substrate is disposed on the lip; a plurality of features to operate in combination with a plurality of heating zones provided by a multi-zonal heating source to provide a desired temperature profile on a frontside surface of a substrate when the substrate is disposed on the lip, and wherein the plurality of features are alternatingly disposed above and below a baseline surface profile of the pocket surface in a radial direction from a central axis of the substrate support.Type: GrantFiled: June 8, 2011Date of Patent: February 14, 2017Assignee: APPLIED MATERIALS, INC.Inventors: Kailash Patalay, Errol Sanchez
