Abstract:
1. A magnetron actuator configured to rotate a magnetron in a magnetron chamber at a back of a sputtering target in a plasma sputter chamber, comprising: first and second separately rotatable shafts extending along an axis and passing from an interior of the magnetron chamber to an exterior thereof; first and second motors disposed externally of the magnetron chamber and coupled to the two shafts; a movable support member supporting the first and second shafts and movable along the axis; a vertical actuator coupled to the movable support member to move it along the axis relative to the target; and a mechanical system coupled to the first and second shafts and supporting a mount for supporting the magnetron, wherein rotations of the first and second shafts are capable of causing the mount to move radially and circumferentially of the axis.
