A graphene and metal interconnect structure and methods of making the same are disclosed. The graphene is a multiple layer graphene structure that is grown using a graphene catalyst. The graphene forms an electrical connection between two or more VIAs or components, or a combination of VIAs and components. A VIA includes a fill metal, with at least a portion of the fill metal being surrounded by a barrier metal. A component may be a routing track, a clock signal source, a power source, an electromagnetic signal source, a ground terminal, a transistor, a macrocell, or a combination thereof. The graphene is grown, using a graphene catalyst, from both solid and liquid carbon sources using chemical vapor deposition (CVD) at a temperature between 300° C.-400° C. The graphene catalyst can be an elemental form of, or alloy including, nickel, palladium, ruthenium, iridium or copper. |
