  • Patent number: 12288672
    Abstract: A method and apparatus for depositing a carbon compound on a substrate includes using an inductively coupled plasma (ICP) chamber with a chamber body, a lid, an interior volume, a pumping apparatus, and a gas delivery system and a pedestal for supporting a substrate disposed within the interior volume of the ICP chamber, the pedestal has an upper portion formed from aluminum nitride with an upper surface that is configured to support and heat a substrate with embedded heating elements and a lower portion with a tube-like structure formed from aluminum nitride that is configured to support the upper portion and house electrodes for supplying power to the embedded heating elements of the upper portion, and the pedestal is configured to heat the substrate during deposition of a carbon compound film.

  • Publication number: 20250037974
    Abstract: Disclosed herein is a processing system. The processing system has an upper chamber body and a lower chamber body defining a processing environment. An upper heater is moveably disposed in the upper chamber body. The upper heater has a moveable support and an upper step formed along an outer perimeter. A lower showerhead is fixedly disposed in the lower chamber body. The lower showerhead includes a top surface configured to support a substrate, a lower step disposed along an outer perimeter wherein the substrate is configured to extend from the top surface partially over the lower step. Lift pins are disposed in the lower showerhead and configured to extend through the top surface and support the substrate thereon. Gas holes are disposed in a first zone along the top surface and a second zone on the step and configured to independently flow both a process and non-process gas.

  • Publication number: 20240160117
    Abstract: Apparatus and method for substrate processing are described herein. More specifically, the apparatus and method are directed towards apparatus and method for performing a field guided post exposure bake operation on a semiconductor substrate. The apparatus is a processing module (100) and includes an upper portion (102) with an electrode (400) and a base portion (104) which is configured to support a substrate (500) on a substrate support surface (159). The upper portion (102) and the base portion (104) are actuated toward and away from one another using one or more arms (112) and form a process volume (404). The process volume (404) is filled with a process fluid and the processing module (100) is rotated about an axis (A). An electric field is applied to the substrate (500) by the electrode (400) before the process fluid is drained from the process volume (404).
