  • Publication number: 20040035361
    Abstract: A two-layer structured electric power application electrode including a non-split electrode consisting of a single planar plate and six split electrodes arranged on the non-split electrode so as to be electrically in contact with the non-split electrode is arranged on the upper side of a discharge chamber provided within a vacuum container such that the power application electrode faces a strip substrate in parallel. The split electrodes are arranged in such a manner as to form a planar plane, and the distance between the surfaces of the split electrodes facing the strip substrate and the strip substrate is uniform. The total area of the surfaces of the split electrodes facing the strip substrate is the same as the area of the non-split electrode on which the split electrodes are mounted. This improves the uniformity in plasma generated in the apparatus for forming a deposited film and enables cutting-down of the costs required to form deposited films.
