  • Patent number: 10242848
    Abstract: A carrier ring for use in a chamber implemented for depositing films and chambers that use the carrier ring are provided. The carrier ring has an annular disk shape with an outer edge side and a wafer edge side. The carrier ring has a top carrier ring surface that extends between the outer edge side to the wafer edge side. The wafer edge side includes a lower carrier ring surface that is lower than the top carrier ring surface. The wafer edge side also includes a plurality of contact support structures. Each contact support structure is located at an edge of the lower carrier ring surface and has a height that is between the lower carrier ring surface and the top carrier ring surface, and the contact support structure has tapered edges and corners. A step is defined between the top carrier ring surface and the lower carrier ring surface, such that a top facing edge is disposed at a top of the step and a lower inner edge is disposed at the bottom of the step.
