▎ 摘　　要

NOVELTY - A graphene laminated substrate comprises graphene with equalized anisotropy laminated in the thickness direction as the lamination direction, and an amorphous carbon film or a boron nitride film as coating layer provided on each opposite surface perpendicular to the lamination direction. USE - Graphene laminated substrate used in thermal radiation equipment used in power semiconductors e.g. metal oxide semiconductor FETs mounted in electric vehicles. ADVANTAGE - The graphene laminated substrate has excellent strength and crack resistance, and high thermal conductivity, and is lightweight. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the composite substrate.
