Declarations under Rule 4.17: — of inventorship (Rule 4.17(iv)) Published: with international search report (Art. 21(3)) (54) Title: BOTTOM AND MIDDLE EDGE RINGS (57) : A bottom ring is configured to support a moveable edge ring. The edge ring is configured to be raised and lowered relative to a substrate support. The bottom ring includes an upper surface that is stepped, an annular inner diameter, an annular outer diameter, a lower surface, and a plurality of vertical guide chan- nels provided through the bottom ring from the lower surface to the upper surface of the bottom ring. Each of the guide channels includes a first region having a smaller diameter than the guide channel, and the guide channels are configured to receive respec- tive lift pins for raising and lowering the edge ring.
