▎ 摘　　要

NOVELTY - Method for synthesizing a graphene pattern, involves physically adhering a catalyst block including a catalyst material to a portion of a growth substrate to form an interface between the catalyst block and the growth substrate, and forming a graphene thin film selectively at the interface between the catalyst block and the growth substrate in an atmosphere including a carbon source and a growth inhibitor. USE - The method is used for synthesizing a graphene pattern, which is used for manufacturing an electro-optical modulator (claimed). ADVANTAGE - The method forms the graphene pattern directly without an individual patterning process, thus improving the efficiency and reliability of manufacturing the electro-optical modulator. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing an electro-optical modulator.
