Abstract:
1. A film depositing apparatus comprising: a process chamber; a gas supply source for supplying gases necessary for film deposition into the process chamber; an evacuating means for evacuating an interior of the process chamber; a target holder provided in the process chamber for holding a target; a substrate holder for supporting a deposition substrate such that the deposition substrate faces the target holder in the process chamber; a power supply for supplying electric power between the target holder and the substrate holder to generate plasma in the process chamber; and an anode provided between the target holder and the substrate holder so as to surround an outer periphery of a side of the substrate holder that faces the target holder for capturing ions and/or electrons in the plasma being generated within the process chamber, wherein the anode includes: a cylindrical member provided so as to surround the outer periphery of the side of the substrate holder that faces the target holder; and at least one annular plate member attached to an inside wall of the cylindrical member, the plate member having a central opening larger than a surface of the deposition substrate.
