▎ 摘　　要

NOVELTY - A board (100) for forming a graphene layer, comprises a board layer (110); a metal catalyst layer (130) disposed on the board layer and functioning as a catalyst for forming the graphene layer; and a stress reduction layer (120) disposed between the board layer and the metal catalyst layer to reduce stress of the metal catalyst layer. USE - As board (100) for forming a graphene layer (claimed). ADVANTAGE - The board having crystallinity and surface roughness suitable for growing a high-quality graphene layer to suppress grain growth from occurring in the course of annealing and induce efficient crystallization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for forming a graphene layer, involving forming a board layer; forming a stress reduction layer on the board layer; forming a metal catalyst layer which functions as a catalyst for forming the graphene layer; and growing the graphene layer on the metal catalyst layer, where the stress reduction layer reduces stress of the metal catalyst layer. DESCRIPTION OF DRAWING(S) - The figure shows view of board for forming a graphene layer. Board (100) Board layer (110) Substrate layer (112) Stress reduction layer (120) Metal catalyst layer (130)
