Classification: CPC H | IPC H

Claim 0:
1. A manufacturing method for an electronic device using graphene, comprising:
forming a first catalytic metal by a first semiconductor process;
forming an electrode having a second catalytic metal by a second semiconductor process;
forming a passivation film and exposing upper surfaces of the first catalytic metal and the second catalytic metal from the passivation film by a third semiconductor process;
forming, after the exposing step, a graphene layer on each of the surfaces of the first catalytic metal and the second catalytic metal which are exposed from the passivation film;
forming, after the graphene layer is formed, an insulation film so as to cover the graphene layer;
forming, after the insulation film is formed, a first substrate on the insulating film; and
removing, after the graphene layer is formed, the first catalytic metal while the electrode including the second catalytic metal is left.
