Width adjustable substrate support for plasma processing

摘要

An electrode assembly for use in a plasma processing system that includes removable rails that are adjustable for reconfiguring the electrode to accommodate substrates of different widths. The electrode assembly includes an electrode having a plurality of first connecting members. Associated with the electrode is a plurality of rails that cooperate for supporting the substrates on the electrode. Each of the rails includes a plurality of second connecting members. Each of the second connecting members is connected detachably with one of the first connecting members for removably mounting the rails with the electrode.
