Patent ID: 11858813
Assignee: GENERAL GRAPHENE CORP.
Field: Materials, metallurgy (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 6:
7. The method for forming graphene of claim 1, wherein said scavenging comprises:
advancing said first surface for processing a scavenging range of lateral distance inside said one or more infeed tunnels;
increasing, during said advancing and inside said one or more infeed tunnels, an incident flow rate of said substrate gas scavenging composition from a lower first incident flow rate value to a higher second incident flow rate value; and
allowing some of said heat, resulting from said annealing temperature and said annealing gas composition used during said annealing, to flow from said one or more processing sub-enclosures in an opposite direction to said advancing of said first surface for processing to said scavenging range of lateral distance inside said one or more infeed tunnels.
