Patent ID: 7195673

Claim:
A plasma CVD apparatus comprising an anode electrode and a cathode electrode, which is for forming a thin film on a substrate by performing plasma discharge between the anode electrode and the cathode electrode, comprising: a substrate holder disposed between the anode electrode and the cathode electrode; and one conductive member disposed between the substrate holder and one electrode of either the anode electrode or the cathode electrode, wherein the substrate holder supports the substrate, the one conductive member is provided between the one electrode and the substrate holder so as to substantially cover an entire space between the one electrode and the substrate holder, the one conductive member is electrically connected to the one electrode and the substrate holder; wherein: the one conductive member includes a supporting plate provided substantially parallel to the one electrode and a plurality of conductive plates provided on an upper surface and a lower surface of the supporting plate; the upper surface of the supporting plate is a surface of the supporting plate opposing the substrate holder; the lower surface of the supporting plate is a surface of the supporting plate opposing the one electrode; the plurality of the conductive plates provided on the upper surface of the supporting plate are in contact with the substrate holder; the plurality of the conductive plates provided on the lower surface of the supporting plate are in contact with the one electrode; the shapes of the plurality of the conductive plates provided on the upper surface and the lower surface of the supporting plate are leaf-spring shapes; the plurality of conductive plates are provided on the upper surface and the lower surface of the supporting plate by attaching one edge of each of the plurality of conductive plates to the supporting plate; and the other edge of each of the plurality of the conductive plates is spaced from the supporting plate.
