Disclosed is a method of forming electrodes on diamond comprising the steps of: forming a mask pattern on diamond or diamond film; performing a treatment of the diamond surface by a plasma of inert gases; forming an electrode film on the whole surface of the specimen; and removing the mask, thereby forming a specified pattern of the electrodes. By this method, it is possible to form electrodes having high adhesion to diamond and diamond film for electronic devices.

Method for forming electrode on diamond for electronic devices

A pair of electrodes 3 are first formed on a substrate. Subsequently, an undoped diamond film is selectively deposited between the above electrodes. A B-doped diamond film is then selectively formed on both the insulating diamond film and part of each electrode. The substrate may be contained in a container provided with an opening portion from which only the B-doped diamond film is exposed.

Diamond film electronic devices

A method for forming diamond films by vapor phase synthesis comprising a process of forming the diamond films on a substrate by direct current discharge plasma, in an atmosphere of a reaction gas including a gas containing at least carbon and hydrogen, or in an atmosphere of a mixed gas containing at least a carbon-containing gas and a hydrogen gas, at a gas pressure between 0.1 and 5 Torr and a substrate temperature between 300.degree. and 1000.degree. C.
