Abstract:
A plasma CVD apparatus comprising a substantially enclosed reaction chamber containing substrate holding means and a cathode electrode in a cylindrical form having a diameter of 5 mm to 10 cm therein, such that a high frequency power from a high frequency power source capable of generating a high frequency with an oscillation frequency of 20 MHz to 600 MHz may be supplied to said cathode electrode from one end side of said cathode electrode to generate plasma between said substrate holding means and said cathode electrode to plasma-process a substrate provided in said substrate holding means,said one end side of said cathode electrode is structured to have an electric conductor comprising a plurality of conductor members shaped in a rod-like form which are arranged substantially along one axis such that said plurality of conductor members are capacitively coupled by a dielectric member, wherein said conductor members are capable of transmitting said high frequency power from said high frequency power source in a direction along said axis.
