  • Patent number: 11869770
    Abstract: Methods, systems, and computer programs are presented for selective deposition of etch-stop layers for enhanced patterning during semiconductor manufacturing. One method includes an operation for adding a photo-resist material (M2) on top of a base material (M1) of a substrate, M2 defining a pattern for etching M1 in areas where M2 is not present above M1. The method further includes operations for conformally capping the substrate with an oxide material (M3) after adding M2, and for gap filling the substrate with filling material M4 after the conformally capping. Further, a stop-etch material (M5) is selectively grown on exposed surfaces of M3 and not on surfaces of M4 after the gap filling. Additionally, the method includes operations for removing M4 from the substrate after selectively growing M5, and for etching the substrate after removing M4 to transfer the pattern into M1. M5 adds etching protection to enable deeper etching into M1.

  • Publication number: 20230369091
    Abstract: A substrate support configured to support a substrate having a diameter D comprises a first inner electrode and a second inner electrode that are each D-shaped, define a first outer diameter that is less than D, and are configured to be connected to an electrostatic chuck voltage to clamp the substrate to the substrate support. An outer electrode comprises a ring-shaped outer portion that surrounds the first inner electrode and the second inner electrode and a center portion that pass between the first inner electrode and the second inner electrode to connect to opposite sides of an inner diameter of the ring-shaped outer portion. The inner diameter of the ring-shaped outer portion is greater than the diameter D such that the inner diameter of the ring-shaped outer portion and intersections between the center portion and the ring-shaped outer portion are located radially outside of the diameter D of the substrate.

  • Patent number: 10745806
    Abstract: Showerheads for independently delivering different, mutually-reactive process gases to a wafer processing space are provided. The showerheads include a first gas distributor that has multiple plenum structures that are separated from one another by a gap, as well as a second gas distributor positioned above the first gas distributor. Isolation gas from the second gas distributor may be flowed down onto the first gas distributor and through the gaps in between the plenum structures of the first gas distributor, thereby establishing an isolation gas curtain that prevents the process gases released from each plenum structure from parasitically depositing on the plenum structures that provide other gases.

  • Patent number: 10643889
    Abstract: A method of improving selectivity of a metal in a selective deposition process. A pre-treatment process for the metal modifies the metal surface, and includes first reducing the metal to remove organic contamination from the metal followed by oxidation of the metal to allow a monolayer of a metal oxide to grow on the surface. This modification of the metal allows inhibitor molecules to adsorb on the metal oxide monolayer to improve selectivity.
