Patent ID: 8641915

Claim:
A method for manufacturing an electronic device, comprising: forming a graphene thin film of a sheet shape by graphene deposition using a vapor carbon supply source, and a SiO 2 substrate including a graphite metal layer, wherein the graphite metal layer includes a graphite metal catalyst, and wherein the graphite metal catalyst includes at least one metal or alloy selected from the group consisting of Ni, Co, Fe, Pt, Au, Al, Cr, Cu, Mg, Mn, Mo, Rh, Si, Ta, Ti, W, U, V, and Zr; preparing a polymer solution with distributed nanoparticles; spin-coating the polymer solution with distributed nanoparticles on a substrate; forming a polymer thin film including the nanoparticles by drying the spin-coated polymer solution, wherein the polymer thin film includes at least one selected from polyvinyl pyrrolidone (PVP), polystyrene (PS), polymethyl methacrylate (PMMA), poly-N-vinylcarbazole (PVK) and polyimide (PI); attaching the graphene thin film to the polymer thin film; patterning the graphene thin film to define a third region between a first region and a second region; and removing the third region to form a first electrode corresponding to the first region and a second electrode corresponding to the second region, the first and second electrodes being substantially coplanar relative to the polymer thin film including the nanoparticles.
