Patent ID: 8877019

Claim:
A sputtering apparatus comprising: a substrate holder including a first stage which can mount a substrate and can rotate about a first rotating shaft, a second stage which can rotate about a second rotating shaft shifted from the first rotating shaft of said first stage, a spinning unit adapted to rotate said first stage about the first rotating shaft, and a revolving unit adapted to revolve said first stage about the second rotating shaft by rotating said second stage about the second rotating shaft; a magnetic field applying unit disposed around a periphery of said second stage to apply a magnetic field in a specific direction to the substrate; and a target mounting table which can mount a target configured to deposit a film on the substrate, wherein said spinning unit rotates said first stage in a direction opposite to a direction of the rotation of said revolving unit, and rotates said first stage so as to maintain the specific direction of the magnetic field applied to the substrate by said magnetic field applying unit.
