▎ 摘　　要

NOVELTY - Graphene substrate comprises a graphene layer, which is folded, and a metal layer, which covers the surface of the graphene layer. USE - Graphene substrate is useful for semiconductor chip (claimed). ADVANTAGE - The graphene substrate can be used as the substrate of the semiconductor chip with high power consumption or high heat flow density. The folded graphene layer can realize the heat transfer in the horizontal and vertical direction, and can reduce the thermal resistance of the chip, enhance the radiating effect. The other metal layer can be connected with the welding component in the chip and solves the problem that the graphene material cannot be welded. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for constructing the graphene substrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of a graphene substrate.
