Abstract:
A multilayer film deposition apparatus comprising:a substrate holder for holding at least one substrate at a position within a predetermined area; a vacuum chamber for retaining the substrate holder and performing sputtering to deposit a film onto said substrate held by said substrate holder; a plurality of cathodes with targets disposed in the vacuum chamber for generating sputter discharge; at least one sputter power source for applying voltage to the plurality of said cathodes; and a main rotation mechanism for rotating the plurality of the targets along a circle, a center axis of the substrate held by the substrate holder being substantially located on the circle so that the plurality of the targets moves over the predetermined area where the at least one substrate held by the substrate holder is located, said predetermined area being defined by a locus of one of the plurality of the targets near a center axis of the circle and a locus thereof away from the axis.
