Aravind KAMATH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11939666
    Abstract: Methods and apparatus for processing a substrate include cleaning and self-assembly monolayer (SAM) formation for subsequent reverse selective atomic layer deposition. An apparatus may include a process chamber with a processing volume and a substrate support including a pedestal, a remote plasma source fluidly coupled to the process chamber and configured to produce radicals or ionized gas mixture with radicals that flow into the processing volume to remove residue or oxides from a surface of the substrate, a first gas delivery system with a first ampoule configured to provide at least one first chemical into the processing volume to produce a SAM on the surface of the substrate, a heating system located in the pedestal and configured to heat a substrate by flowing gas on a backside of the substrate, and a vacuum system fluidly coupled to the process chamber and configured to control heating of the substrate.

  • Publication number: 20220099426
    Abstract: Methods and apparatus for substrate position calibration for substrate supports in substrate processing systems are provided herein. In some embodiments, a method for positioning a substrate on a substrate support includes: obtaining a plurality of backside pressure values corresponding to a plurality of different substrate positions on a substrate support by repeatedly placing a substrate in a position on the substrate support, and vacuum chucking the substrate to the substrate support and measuring a backside pressure; and analyzing the plurality of backside pressure values to determine a calibrated substrate position.
