Graphene-clad metal interconnect and method of forming the same

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...

Zusammenfassung: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.
