▎ 摘　　要

NOVELTY - A carbon-based electronic device consists of a substrate (10), a graphene oxide layer (20) formed on the substrate, a gate insulation layer (40) formed on the graphene oxide layer, and a gate electrode (50) formed on the gate insulation layer. The graphene oxide layer is partially reduced by irradiating one surface of graphene oxide layer using laser beam. USE - Carbon-based electronic device e.g. thin-film transistor (claimed) is used for optical device and memory device. ADVANTAGE - The carbon-based electronic device has excellent transparency and reduced resistance, and is manufactured with high productivity, without performing etching process, by fast and economical process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of carbon-based electronic device, which involves forming the graphene oxide layer on the substrate, providing a mask on the formed graphene oxide layer, irradiating and patterning the mask and removing, and irradiating the graphene oxide layer using laser. DESCRIPTION OF DRAWING(S) - The drawing shows the cross-sectional view of the carbon-based electronic device.
