Abstract
An electrode assembly for a plasma reaction chamber used in semiconductor substrate processing having a backing member having a bonding surface, an inner electrode having a lower surface on one side and a bonding surface on the other side, and an outer electrode having a lower surface on one side and a bonding surface on the other side. At least one of the electrodes has a flange, which extends underneath at least a portion of the lower surface of the other electrode.
