  • Patent number: 10407771
    Abstract: Methods and apparatus for cleaning an atomic layer deposition chamber are provided herein. In some embodiments, a chamber lid assembly includes: a housing enclosing a central channel that extends along a central axis and has an upper portion and a lower portion; a lid plate coupled to the housing and having a contoured bottom surface that extends downwardly and outwardly from a central opening coupled to the lower portion of the central channel to a peripheral portion of the lid plate; a first heating element to heat the central channel; a second heating element to heat the bottom surface of the lid plate; a remote plasma source fluidly coupled to the central channel; and an isolation collar coupled between the remote plasma source and the housing, wherein the isolation collar has an inner channel extending through the isolation collar to fluidly couple the remote plasma source and the central channel.
    Type: Grant
    Filed: October 6, 2014

  • Patent number: 8618446
    Abstract: Apparatus for processing a substrate are provided herein. In some embodiments, a substrate support includes a substrate support surface and a shaft; an RF electrode disposed in the substrate support proximate the substrate support surface to receive RF current from an RF source; a heater disposed proximate the substrate support surface to provide heat to a substrate when disposed on the substrate support surface, the heater having one or more conductive lines to provide power to the heater; a thermocouple to measure the temperature of a substrate when disposed on the substrate support surface; and a conductive element having an interior volume with the one or more conductive lines and the thermocouple disposed through the interior volume, the conductive element coupled to the RF electrode and having an electric field of about zero in the interior volume when RF current is flowed through the conductive element.
