Patent attributes
A pedestal positioning assembly system for use in a substrate processing system includes a pedestal rigidly attached to a pedestal shaft, a reference rigidly attached to the substrate processing system, a lateral adjustment assembly to adjust a lateral location of the pedestal relative to the reference, and a vertical adjustment assembly to adjust a tilt of the pedestal relative to the reference. The lateral adjustment assembly and the vertical adjustment assembly are external to a processing chamber and are coupled to the pedestal disposed within the processing chamber through the pedestal shaft. The reference can be a ring and the lateral adjustment assembly substantially centers the pedestal within the ring. A method of adjusting a pedestal includes leveling the pedestal, translating the pedestal, calibrating the pedestal height to a preheat ring level, and checking the level and location of the pedestal while rotating the pedestal.
