▎ 摘　　要

NOVELTY - The method involves forming a metallic layer on a silicon layer. A graphene layer is formed between the silicon layer and the metallic layer. A thermal process is performed at hydrogen atmosphere. A carbon containing polymer material is coated on the silicon layer. USE - Electric component formation method. ADVANTAGE - The method enables providing diffusion preventing characteristic to prevent RC retardation phenomenon based on conductivity. The method enables reducing thickness of a diffusion barrier and wiring interval of an electric component. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of an electric component.
