  • Publication number: 20220100088
    Abstract: Metal-comprising resist layers (for example, metal oxide resist layers), methods for forming the metal-comprising resist layers, and lithography methods that implement the metal-comprising resist layers are disclosed herein that can improve lithography resolution. An exemplary method includes forming a metal oxide resist layer over a workpiece by performing deposition processes to form metal oxide resist sublayers of the metal oxide resist layer over the workpiece and performing a densification process on at least one of the metal oxide resist sublayers. Each deposition process forms a respective one of the metal oxide resist sublayers. The densification process increases a density of the at least one of the metal oxide resist sublayers. Parameters of the deposition processes and/or parameters of the densification process can be tuned to achieve different density profiles, different density characteristics, and/or different absorption characteristics to optimize patterning of the metal oxide resist layer.

  • Patent number: 11257755
    Abstract: The present disclosure describes a method for forming a barrier structure between liner-free conductive structures and underlying conductive structures. The method includes forming openings in a dielectric layer disposed on a contact layer, where the openings expose conductive structures in the contact layer. A first metal layer is deposited in the openings and is grown thicker on top surfaces of the conductive structures and thinner on sidewall surfaces of the openings. The method further includes exposing the first metal layer to ammonia to form a bilayer with the first metal layer and a nitride of the first metal layer, and subsequently exposing the nitride to an oxygen plasma to convert a portion of the nitride of the first metal layer to an oxide layer. The method also includes removing the oxide layer and forming a semiconductor-containing layer on the nitride of the first metal layer.

  • Publication number: 20220051952
    Abstract: A deposition system provides a feature that may reduce costs of the sputtering process by increasing a target change interval. The deposition system provides an array of magnet members which generate a magnetic field and redirect the magnetic field based on target thickness measurement data. To adjust or redirect the magnetic field, at least one of the magnet members in the array tilts to focus on an area of the target where more target material remains than other areas. As a result, more ion, e.g., argon ion bombardment occurs on the area, creating more uniform erosion on the target surface.
