  • INTEGRATED METHODS FOR GRAPHENE FORMATION
    Publication number: 20230017035
    Abstract: A method of forming graphene layers is disclosed. The method includes precleaning the substrate with a plasma formed from an argon- and hydrogen-containing gas, followed by forming a graphene layer by exposing the substrate to a microwave plasma to form a graphene layer on the substrate. The microwave plasma comprises hydrocarbon and hydrogen radicals. The substrate is then cooled. A capping layer may also be formed.
