Abstract:
A plasma CVD apparatus comprisinga deposition chamber comprising a pair of electrodes, one of which is configured to carry a deposition target object; power applying means which is configured to apply an electric power, wherein said power applying means comprises radio-frequency (RE) power applying means and direct current (DC) power applying means, wherein said DC power applying means is configured to apply power to said electrode which is configured to carry the deposition target object; and a deposition material gas supply unit which is configured to supply said deposition chamber (1) as a deposition material gas, a gas of a carbon compound or a gas of a carbon compound together with a gas of a kind different from said carbon compound gas other than nitrogen or ammonia gas, for depositing a carbon film on the deposition target object, and (2) either or both a nitrogen gas and an ammonia gas, together with said deposition material gas, immediately before completion of the deposition of the carbon film with the continued application of the power by said power applying means thereby allowing the formation of a carbon nitride plasma which upon deposition forms a carbon nitride film layer on the surface of the carbon film.
