▎ 摘　　要

NOVELTY - Manufacture of graphene layer laminated-diamond substrate involves contacting diamond substrate with a metal material made of one or more metals chosen from nickel, iron, cobalt, copper and chromium, heating the diamond substrate at 600-1300 degrees C in hydrogen gas or inert gas atmosphere, and cooling the diamond substrate. USE - Manufacture of graphene layer laminated-diamond substrate used for manufacture of semiconductor devices. ADVANTAGE - The method is economical and provides high quality product with increased productivity.
