ABSTRACT:
A confinement ring support assembly for coupling together a plurality of confinement rings in a plasma processing chamber. The confinement ring support assembly includes a post having first end and a second end. The post further includes a first lip having an associated first sliding surface, and a second lip having an associated second sliding surface. The first lip is disposed at a first position on the post, the second lip being disposed at a second position at a different arc relative to the first location on the post, the second position being disposed between the first position and the first end along a longitudinal axis of the post. The confinement ring support assembly further includes a first washer configured to move slidably from the first lip past the second lip toward the first end of the post. The first washer has a first cut formed in its interior opening that is configured to engage with the first lip to prevent the first washer from sliding past the first lip in a direction away from the first end and to engage with the first sliding surface associated with the first lip to constrain a rotational movement of the first washer as the washer moves longitudinally along the post.
