    摘要: A DC plasma jet CVD process having a high film deposition rate is employed. A material having low adhesion with diamond is used for a substrate. A diamond film automatically peels from the substrate at the time of cooling. Gas is recycled because gas utilization efficiency is low. In this case, deposition of carbon can be prevented by setting a gas flow velocity to at least 5 m/s in the proximity of an anodic point.
