Abstract:
1. A plasma confinement system comprising: an electrical ground; a containment device coupled to the electrical ground, the containment device acting as a first electrode having a surface facing an interior of the containment device; a process gas source coupled to the containment device; a second electrode having a surface facing the interior of the containment device that is proximate and substantially parallel to the first electrode; a first volume disposed between the first and the second electrodes; and a second volume disposed next to the first volume, wherein the first volume and the second volume are separated by one side adjacent to both the first volume and the second volume; wherein the containment device comprises the one side, the containment device substantially enclosing the first volume and electrically coupled to the electrical ground, the one side comprising at least one channel that allows gas to pass between the first volume and second volume, wherein the at least one channel is configured to maintain a pressure level of at least one of the first volume and the second volume.
