Abstract:
1. A sputtering apparatus including a sputtering target made of a deposition material and at least one substrate that are disposed in a vacuum chamber so as to be opposed to each other with a predetermined distance therebetween, the apparatus being used for forming a coating film made of the deposition material constituting the sputtering target on the at least one substrate by sputtering, wherein a substrate supporting device is provided in the vacuum chamber to support the at least one substrate, and the substrate supporting device comprises: at least one supporting member supporting the at least one substrate so as to be opposed to the sputtering target, the at least one supporting member being disposed in the vacuum chamber in a rotatable manner around a first rotation axis and a second rotation axis, the first rotation axis extending in a first direction orthogonal to a direction in which the at least one substrate and the sputtering target are opposed to each other and the second rotation axis extending in a second direction orthogonal to both of the first direction and the direction in which the at least one substrate and the sputtering target are opposed to each other, the at least one supporting member being each provided with the second rotation axis, a first driving mechanism including a first driving unit generating a predetermined rotation driving force to rotationally drive the at least one supporting member around the first rotation axis; and a second driving mechanism including a second driving unit generating a predetermined rotation driving force to rotationally drive the at least one supporting member around the second rotation axis, wherein the first rotation axis and the second rotation axis are connected via a retaining bar that extends from the first rotation axis in a horizontal direction orthogonal to an extending direction of the first rotation axis and being provided with the second rotation axis at an extended tip portion of the retaining bar.
