Abstract:
In combination for providing a controlled deposition on a plurality of substrates,a turntable rotatable on a first axis,a plurality of planets each operatively coupled to the turntable for rotation with the turntable during the rotation of the turntable and each independently rotatable on a second axis displaced from the first axis,a stator rotatable on the first axis and operatively coupled to the planets for rotating the planets on the second axis,first means for providing a coupling between the turntable and the stator in a first relationship to provide a rotation of the stator with the turntable and for providing a decoupling of the stator from the turntable in a second relationship,second means for providing a first movement of the planets on the first axis when the turntable is rotated in the first relationship,third means for providing a second movement of the planets on the first axis when the turntable is rotated in the second relationship, andfourth means for providing a rotation of the planets on the second axis independently of any movement of the turntable and the stator to position the planets for the transfer of the substrates to the planets.
