    Abstract: An improved interconnect structure including a dielectric layer (202) having a conductive feature (204) embedded therein, the conductive feature (204) having a first top surface (208) that is substantially coplanar with a second top surface (206) of the dielectric layer (202); a metal cap layer (212) located directly on the first top surface (208), wherein the metal cap layer (212) does not substantially extend onto the second top surface (206); a first dielectric cap layer (21 0A) located directly on the second top surface (206), wherein the first dielectric cap layer (21 0A) does not substantially extend onto the first top surface (208) and the first dielectric cap layer (210A) is thicker than the metal cap layer (212); and a second dielectric cap layer (220) on the metal cap layer (212) and the first dielectric cap layer (210A). A method of forming the interconnect structure is also provided.

    Abstract: A graphene and metal interconnect structure and methods of making the same. A multiple layer graphene structure may be grown using a graphene catalyst. The graphene forms an electrical connection 30 between two or more vias (16,36) or components 20, or a combination of vias and components. A via includes a fill metal, with at least a portion of the fill metal 36 being surrounded by a barrier metal 38. 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.
