  • 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.

  • Patent number: 11756784
    Abstract: A method of cleaning a surface of a substrate uses alcohol and water treatments. The method may include applying an alcohol treatment on a surface of the substrate with the alcohol treatment configured to provide surface reduction and applying a water treatment to the surface of the substrate with the water treatment configured to enhance selectivity of at least a portion of the surface for a subsequent barrier layer process by removing alcohol from the at least a portion of the surface. The water treatment may be performed simultaneously with the alcohol treatment or performed after the alcohol treatment. The water treatment may include vaporized water or water injected into a plasma to produce hydrogen or oxygen radicals.

  • Publication number: 20230253248
    Abstract: Methods of forming devices comprise forming a dielectric layer on a substrate, the dielectric layer comprising at least one feature defining a gap including sidewalls and a bottom. The methods include selectively depositing a self-assembled monolayer (SAM) on the bottom of the gap. The SAM comprises a hydrocarbon having a formula of H—C?C—R, wherein R is a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms or a formula of R?C?CR?, wherein R? and R? independently include a linear alkyl chain or aryl group comprising from 1 to 20 carbon atoms A barrier layer is formed on the SAM before selectively depositing a metal liner on the barrier layer. The SAM is removed after selectively depositing the metal liner on the barrier layer.

  • Publication number: 20230212747
    Abstract: Methods and apparatus for self-assembled monolayer (SAM) deposition are provided herein. In some embodiments, an apparatus for self-assembled monolayer (SAM) deposition includes: a chamber enclosing a processing volume; a substrate support disposed in the chamber and configured to support a substrate in the processing volume; a gas distribution system coupled to the chamber and configured to distribute a process gas into the processing volume; a first SAM precursor source fluidly coupled to the gas distribution system to provide a first SAM precursor as a part of the process gas; and a second SAM precursor source fluidly coupled to the gas distribution system to provide a second SAM precursor, different than the first SAM precursor, as a part of the process gas, wherein the first and second SAM precursor sources are independently controllable to control a relative percentage of the first and second SAM precursors in the process gas with respect to each other.
