A plasma processing chamber configured for cleaning a bevel edge of a substrate is provided. The chamber includes a top edge electrode surrounding an insulating plate, and the insulator plate opposes a bottom electrode. The top edge electrode is electrically grounded and separated from the insulator plate by a top dielectric ring. The chamber also includes a bottom edge electrode that is electrically grounded and surrounds the bottom electrode and is separated from the bottom electrode by a bottom dielectric ring. The bottom edge electrode is oriented to oppose the top edge electrode, and the bottom edge electrode has an L shape that is up-facing. Bevel edge plasma processing of a substrate edge is configured to be processed in a chamber having the top and bottom edge electrodes.
