Abstract: Process chambers having a tunable showerhead and a tunable liner are disclosed herein. In some embodiments, a processing chamber includes a showerhead; a chamber liner; a first impedance circuit coupled to the showerhead to tune an impedance of the showerhead; a second impedance circuit coupled to the chamber liner to tune an impedance of the chamber liner; and a controller coupled to the first and second impedance circuits to control relative impedances of the showerhead and the chamber liner.

Abstract: An electrostatic chuck is described that has radio frequency coupling suitable for use in high power plasma environments. In some examples, the chuck includes a base plate, a top plate, a first electrode in the top plate proximate the top surface of the top plate to electrostatically grip a workpiece, and a second electrode in the top plate spaced apart from the first electrode, the first and second electrodes being coupled to a power supply to electrostatically charge the first electrode.

Abstract: In some embodiments, a plasma processing apparatus includes a processing chamber to process a substrate; a mounting surface defined within the processing chamber to support a substrate disposed within the processing chamber; a showerhead disposed within the processing chamber and aligned so as to face the mounting surface, the showerhead defining a plurality of orifices to introduce a process gas into the processing chamber toward a substrate disposed within the processing chamber; and one or more magnets supported by the showerhead and arranged so that a radial component of a magnetic field applied by each of the one or more magnets has a higher flux density proximate a first region corresponding to an edge surface region of a substrate when disposed within the processing chamber than at a second region corresponding to an interior surface region of a substrate when disposed within the processing chamber.
