<p>A multi-segment electrode assembly having a plurality of electrode segments for modifying a plasma in a plasma processing chamber is disclosed. There is included a first powered electrode segment having a first plasma-facing surface, the first powered electrode segment configured to be powered by a first RE signal. There is also included a second powered electrode segment having a second plasma-facing surface, the second powered electrode segment configured to be powered by a second RE signal. The second powered electrode segment is electrically insulated from the first powered electrode segment, while at least one of the first plasma-facing surface and the second plasma-facing surface is non-planar.</p> |
