Claim 12:
13. A plasma processing apparatus, comprising:
a plasma generator;
a processing chamber operable to receive a workpiece within a processing region of the processing chamber, wherein the processing chamber comprises:
a first electrode characterized by a first surface and a second surface opposite the first surface, wherein the first electrode defines a plurality of first apertures extending therethrough;
a second electrode characterized by a first surface facing the second surface of the first electrode and a second surface opposite the first surface of the second electrode, wherein the second electrode defines a plurality of second apertures extending therethrough, wherein a gap distance is formed between the first electrode and the second electrode;
one or more adjustable couplers operable to adjust one or more of translation or rotation of the first electrode with respect to the second electrode; and
a substrate support disposed beneath the first electrode and the second electrode, a topmost surface of the substrate support being spaced apart from the first electrode and the second electrode.
