▎ 摘　　要

NOVELTY - The system has a gas blower that comprises a storage which is configured for storing the carbon-included gas (300). A heating portion is configured for heating the carbon-included gas with a constant temperature. A piezo injection system is configured for showing the carbon-included gas and performing the gas injection by operating a solenoid valve module and a piston module and opening of a needle in an order, by applying a voltage. USE - Solenoid injection system for use in manufacture of noncatalytic substrate growth graphene used in electronic component. ADVANTAGE - The catalyst metal on the substrate is not used for the manufacture of the noncatalytic substrate growth graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating the process of manufacturing noncatalytic substrate growth graphene. Step for growing graphene on substrate (1) Step for supplying carbon-included gas (2) Board layer (100) Carbon-included gas (300) Graphene (500)
