Patent ID: 8461028

Claim:
A method for synthesizing graphene, the method comprising: patterning and etching a first set of regions of a dielectric layer located on a silicon substrate; depositing a metal barrier onto said dielectric layer; depositing a metal onto said metal barrier forming a stack of said metal/metal barrier; annealing said metal/metal barrier stack; performing a chemical mechanical polishing of said metal following said deposition of said metal onto said metal barrier whereby said metal resides in said first set of regions of said dielectric layer after said chemical mechanical polishing is performed; patterning and etching photoresist mask regions to cover a second set of regions of said dielectric layer, wherein said second set of regions does not overlap with said first set of regions; implanting carbon in said metal via ion implantation, wherein said carbon is distributed in said metal; removing said photoresist mask regions; annealing said metal with said implanted carbon; and cooling said metal with said implanted carbon after said annealing in order to precipitate said carbon from said metal by diffusion to form a layer of graphene on a surface of said metal.
