  • Publication number: 20230402384
    Abstract: Material properties of graphene can be leveraged to improve performance of interconnects in an integrated circuit. One way to circumvent challenges involved in depositing graphene onto a copper surface is to incorporate graphene into the bulk metal layer to create a hybrid metal/graphene interconnect structure. Such a hybrid structure can be created instead of, or in addition to, forming a graphene film on the metal surface as a metal capping layer. A first method for embedding graphene into a copper damascene layer is to alternate the metal fill process with graphene deposition to create a composite graphene matrix. A second method is to implant carbon atoms into a surface layer of metal. A third method is to disperse graphene flakes in a damascene copper plating solution to create a distributed graphene matrix. Any combination of these methods can be used to enhance conductivity of the interconnect.

  • Publication number: 20230402385
    Abstract: A graphene-clad metal interconnect extends material properties of graphene to both damascene and patterned interconnect structures at lower metal layers, leading to significant reductions in resistance. Graphene cladding can be used with or without a metal barrier/liner. Presence of a barrier/liner can serve to catalyze growth of an overlying graphene layer. Graphene may also be selectively grown on barrier surfaces. Fully integrated structures and process flows for integrated circuits with graphene-clad metallization are described.
