Abstract:
1. A sputtering apparatus comprising: a cathode having a sputtering target supporting surface, the sputtering target supporting surface being rotatable about a first rotating shaft; a stage having a substrate supporting surface, the substrate supporting surface being rotatable about a second rotating shaft disposed parallel to the first rotating shaft; and a shielding plate disposed between the sputtering supporting surface and the substrate supporting surface that is rotatable about the first rotating shaft or the second rotating shaft, wherein the rotation of at least one of the sputtering target supporting surface, the substrate supporting surface and the shielding plate is controlled so that sputtered particles impinging at an angle formed with respect to a normal line of the substrate supporting surface of 0° or more and 50° or less out of sputtered particles generated from the sputtering target supported on the sputtering target supporting surface during sputtering are made to impinge on the substrate supported on the substrate supporting surface, and when sputtering is performed with a target disposed on the sputtering target supporting surface, at least part of a first end in a rotation direction of the shielding plate is positioned in a region surrounded by an aggregate of regions where a vertical component of a magnetic field generated from the cathode of the target disposed in the cathode with respect to the sputtering target supporting surface becomes 0.
