Patent number: 4915977Abstract: A method of forming a diamond film on a substrate wherein hydrogen, a hydrocarbon series gas, an inert gas, an organic compound series gas or a mixture of such gases is introduced into a vacuum vessel to contact a substrate and carbon is evaporated by are discharge at a carbon cathode while applying a voltage to the substrate to deposit carbon on the substrate thus forming a diamond film on the substrate. A silicon series gas, a germanium series gas or a mixture thereof may be also introduced into the vessel with the foregoing gas or gases. While the carbon is being deposited on the substrate, thermoelectrons may also be supplied onto the substrate, and, further, high frequency discharge may be generated in a space between the substrate and the cathodes.Type: GrantFiled: February 25, 1988Date of Patent: April 10, 1990Assignee: Nissin Electric Co., Ltd.Inventors: Koji Okamoto, Masayasu Tanjo, Eiji Kamijo
