Abstract:
A method of mounting an electrode assembly on a plasma etching apparatus, the mounting method comprising:inserting each of a plurality of alignment pins in a respective one of a plurality of apertures in the plasma etching apparatus such that each alignment pin extends from one of said plurality of apertures and has a central axis that extends along an entire length of that alignment pin and that passes through a center of said one of said plurality of apertures; aligning a plurality of apertures in the electrode assembly relative to the alignment pins such that said central axis of each of said alignment pins extends through a center of one of said plurality of apertures in said electrode assembly; mounting the electrode assembly on and in proper alignment with the plasma etching apparatus by passing the alignment pins through the apertures of the electrode assembly; and replacing each of the alignment pins with a fastener.
