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.
