  • Patent number: 11171023
    Abstract: Embodiments of the present disclosure generally relate to apparatus and methods for semiconductor processing, more particularly, to a thermal process chamber. The thermal process chamber may include a substrate support, a first plurality of heating elements disposed over the substrate support, and one or more high-energy radiant source assemblies disposed over the first plurality of heating elements. The one or more high-energy radiant source assemblies are utilized to provide local heating of cold regions on a substrate disposed on the substrate support during processing. Localized heating of the substrate improves temperature profile, which in turn improves deposition uniformity.
    Type: Grant
    Filed: October 7, 2016
    Date of Patent: November 9, 2021
    Assignee: Applied Materials, Inc.
    Inventors: Schubert S. Chu, Douglas E. Holmgren, Kartik Shah, Palamurali Gajendra, Nyi O. Myo, Preetham Rao, Kevin Joseph Bautista, Zhiyuan Ye, Martin A. Hilkene, Errol Antonio C. Sanchez, Richard O. Collins
  • Patent number: 10519547
    Abstract: Embodiments of the present disclosure generally relate to a susceptor for thermal processing of semiconductor substrates. In one embodiment, the susceptor includes a first rim, an inner region coupled to and surrounded by the first rim, and one or more annular protrusions formed on the inner region. The one or more annular protrusions may be formed on the inner region at a location corresponding to the location where a valley is formed on the substrate, and the one or more annular protrusions help reduce or eliminate the formation of the valley.
