    摘要: A method for processing a workpiece in a plasma reactor chamber having radially inner and outer source power applicators at a ceiling of the chamber facing the workpiece, the inner and outer source power applicators and the workpiece sharing a common axis of symmetry. The method includes applying RF source power to the source power applicator, and introducing a process gas into the reactor chamber so as to carry out a plasma process on the workpiece characterized by a plasma process parameter, the plasma process parameter having a spatial distribution across the surface of the workpiece. The method further includes rotating at least the outer RF source power applicator about a radial tilt axis to a position at which the spatial distribution of the plasma process parameter has at least a nearly minimal non-symmetry relative to the common axis of symmetry, and translating the inner source power applicator relative to the outer source power applicator along the axis of symmetry to a location at which the spatial distribution has at least a nearly minimal non-uniformity across the surface of the workpiece.
