Abstract: An apparatus includes a plasma process chamber and a support element capable of supporting a substrate inside the plasma process chamber. At least one plasma control element is placed adjacent to a peripheral portion of the support element such that the plasma control element is capable of influencing a plasma inside the plasma process chamber if an electric field is applied thereto. At least one voltage generator is connected to the plasma control element. The plasma control element is movable inside the process chamber such that it can be set to any of at least two different positions.

Abstract: A plasma processing device includes at least one process chamber for receiving an article, for example a wafer, that is to be processed using a plasma. The process chamber has a prescribed chamber construction. A flow-influencing apparatus is arranged in the process chamber and set in such a manner that an asymmetrical inner space is produced within the process chamber thereby changing a flow behavior of a process gas contained in the process chamber.
