  • Patent number: 11348832
    Abstract: A self-aligned via interconnect structures and methods of manufacturing thereof are disclosed. The method includes forming a wiring structure in a dielectric material. The method further includes forming a cap layer over a surface of the wiring structure and the dielectric material. The method further includes forming an opening in the cap layer to expose a portion of the wiring structure. The method further includes selectively growing a metal or metal-alloy via interconnect structure material on the exposed portion of the wiring structure, through the opening in the cap layer. The method further includes forming an upper wiring structure in electrical contact with the metal or metal-alloy via interconnect structure.
    Type: Grant
