Plasma treatment apparatus and method
A substrate is held in a substrate holder and accommodated in a treatment chamber. A positive electrode panel is arranged opposite to a surface of the substrate. Process gas is sent from a blower panel, toward the positive electrode panel and the substrate. A positive electrode of a high-frequency power source is connected to the positive electrode panel, and a negative electrode of the high-frequency power source is connected to the blower panel, to apply a high-frequency voltage. The process gas passes between the positive electrode panel and the blower panel which is the negative electrode, so that plasma is generated. The generated plasma removes contaminants on the surface of the substrate.

PLASMA UNIFORMITY CONTROL IN PULSED DC PLASMA CHAMBER
Embodiments provided herein generally include apparatus, e.g., plasma processing systems and methods for the plasma processing of a substrate in a processing chamber. In some embodiments, aspects of the apparatus and methods are directed to improving process uniformity across the surface of the substrate, reducing defectivity on the surface of the substrate, or both. In some embodiments, the apparatus and methods provide for improved control over the uniformity of a plasma formed over the edge of a substrate and/or the distribution of ion energies at the surface of the substrate. The improved control over the plasma uniformity may be used in combination with substrate handling methods, e.g., de-chucking methods, to reduce particulate-related defectivity on the surface of the substrate. In some embodiments, the improved control over the plasma uniformity is used to preferentially clean accumulated processing byproducts from portions of the edge ring during an in-situ plasma chamber cleaning process.
SYSTEMS AND METHODS OF PLASMA GENERATION WITH MICROWAVES
Plasma generators and methods of generating plasma are disclosed. Electrodes in a reaction zone are energized by a high voltage power source that is electrically insulated from the electrodes. A first conductor array, preferably a coil, is electrically coupled to the power source and electrically insulated from the electrodes. A second conductor array, preferably a coaxial coil nested within the first conductor array, is electrically coupled to the electrodes. Electromagnetic induction between the first conductor array and the second conductor array is used to energize the electrodes and generate a plasma in the reaction zone. One or more microwaves are further directed at the plasma to form microwave plasma, either in parallel or in series. Such plasmas are used to reform a hydrocarbon feedstock into low C hydrocarbons, carbon, or hydrogen. Plasma generators combining induction plasma with serial microwave plasmas are further contemplated.
