Abstract:
1. A film deposit apparatus for forming an ITO film, having at least two magnetron sputtering units arranged in a film deposit chamber in a substrate transfer direction to convey substrates while sequentially arranging the substrates opposite each of the magnetron sputtering units in the substrate transfer direction and to sequentially perform sputtering deposit while the substrates are opposed to each of the magnetron sputtering units during conveyance of the substrates, characterized in that: each of the magnetron sputtering units comprises: a magnet reciprocating in a substrate transfer direction, a target, a target shield of a floating structure provided adjacent to an outer-periphery portion of the target and electrically insulated, and cathode shields provided adjacent to the outside of the target shield, and a first cathode shield of the cathode shields provided on the magnetron sputtering unit disposed on the most upstream side in the substrate transfer direction, is of a floating structure electrically insulated, and a second cathode shield, which comprises succeeding cathode shields in the substrate transfer direction, is connected to a ground potential.
