    Abstract: A vacuum plasma processor includes a coil for reactively exciting a plasma so plasma incident on a workpiece has substantially uniformity. The coil and a window which reactively couples fields from the coil to the plasma have approximately the same diameter. An r.f. source supplies a pulse amplitude modulated envelope including an r.f. carrier to the coil.

    Abstract: A plasma processing system having at least a plasma processing chamber for performing plasma processing of a substrate and utilizing at least a first processing state and a second processing state. Plasma is present above the center region of the substrate during the first processing stale to perform plasma processing of at least the center region during the first processing state. Plasma is absent above the center region of the substrate but present adjacent to the bevel edge region during the second processing state to at least perform plasma processing of the bevel edge region during the second processing state. During the second processing state, the upper electrode is in an RF floating state and the substrate is disposed on the lower electrode surface.

    Abstract: A vacuum plasma processor for treating a workpiece with an RF plasma has a plasma excitation coil including a peripheral portion supplying a substantial magnetic flux density to peripheral portions of the plasma. Additional conducting segments spatially adjacent to and electrically connected to a segment of the peripheral portion supply additional magnetic flux having a substantial magnetic flux density to the plasma peripheral portions. The additional conductor segments are in each of four corners of the coil, being connected electrically in parallel or series to coil conductor segments forming the corners. In another embodiment, the coil includes several nested conducting corner segments. In different embodiments, the corner segments are (1) coplanar with the remainder of the coil and (2) closer to the plasma than the remainder of the coil. The coil includes two electrically parallel, spiral like windings, each with an interior terminal connected to one output terminal of a matching network and an output terminal connected via a capacitor to another output terminal of the matching network. The capacitor values and the lengths of the windings relative to the plasma RF excitation wavelength are such that current flowing in the coil has maximum and minimum standing wave values in the peripheral and interior coil portions, respectively. The coil and workpiece peripheries have similar rectangular dimensions and geometries.
