▎ 摘　　要

NOVELTY - The conductive film comprises a fine catalytic metal particle as a junction, a graphene extending in a network form from the junction, and a graphene, which is free from the fine catalytic metal particle, stacked over the graphene extending in the network form from the junction. The conductive film has a three-dimensional structure. USE - The conductive film is useful in a semiconductor device (claimed) such as a large scale integration or a photoelectric conversion device including a solar cell, and useful as a three-dimensional wiring containing an integrated combination of transverse and vertical wirings. ADVANTAGE - The conductive film improves current-density resistance, mobility, heat resistance and mechanical strength of the semiconductor device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a semiconductor device. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a semiconductor device.
