    Abstract: A plasma processing chamber is provided. The plasma processing chamber includes a bottom electrode configured to support a substrate and a top electrode located over the bottom electrode. The plasma processing chamber further includes a plasma confinement assembly designed to transition between a closed orientation and an open orientation. In the closed orientation, the plasma confinement assembly defines a first volume for plasma during processing, and in the open orientation, the plasma confinement assembly defines a second volume for plasma during processing which is larger than the first volume.
