Claim:
An oblique sputtering apparatus comprising: a cathode including a target supporting surface which supports a target of a sputtering material, the cathode being provided with a first rotation axis around which the target supporting surface rotates; a stage including a substrate supporting surface, the stage being provided with a second rotation axis around which the substrate supporting surface rotates; and a control device for controlling the rotation of the cathode and the stage, wherein: the first rotation axis and the second rotation axis are arranged in parallel with each other, and the target supporting surface is supported by the cathode so as to become parallel to the first rotation axis; the target supporting surface and the substrate supporting surface are arranged to face each other; and wherein the control device controls the rotation of the cathode and the stage during sputtering so that the cathode and the stage respectively rotate in the same rotation direction and the target supporting surface and the substrate supporting surface move so as to pass each other while facing each other in parallel; the control device controls the rotation of the cathode and the stage so that the rotation of the cathode is started from a position where the cathode inclines about the first rotation axis in a first direction with respect to a horizontal plane and is terminated at a position where the cathode inclines about the first rotation axis in a second direction with respect to the horizontal plane, and the rotation of the stage is started from a position where the stage inclines about the second rotation axis in the second direction with respect to the horizontal plane and is terminated at a position where the stage inclines about the second rotation axis in the first direction with respect to the horizontal plane; and wherein angular velocities of the rotations of the cathode and the stage are maximized when the target supporting surface and the substrate supporting surface face each other in parallel, and the angular velocities of the rotations of the cathode and the stage are minimized when the rotation of the cathode and the stage is started or terminated.
