Claim 0:
1. An apparatus for distributing plasma products, comprising:
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 is disposed beneath the first electrode;
the second electrode defines a plurality of apertures that are configured to permit at least one of plasma, free electrons, or ionic species to pass into a processing region that is configured to receive a substrate for processing;
the second electrode forms at least one component selected from the group consisting of a faceplate, a showerhead, an ion suppressor, and a plasma blocking screen;
the second electrode defines a plurality of second apertures extending therethrough; and
a gap distance is formed between the first electrode and the second electrode; and

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.
