    摘要: A method for etching a feature in a low-k dielectric layer through a photoresist etch mask over a substrate. A gas-modulated cyclic stripping process is performed for more than three cycles for stripping a single photoresist mask. Each cycle of the gas-modulated cyclic stripping process comprises performing a protective layer formation phase and a stripping phase. The protective layer forming phase using first gas chemistry with a deposition gas chemistry, wherein the protective layer forming phase is performed in about 0.005 to 10 seconds for each cycle. The performing the stripping phase for stripping the photoresist mask using a second gas chemistry using a stripping gas chemistry, where the first gas chemistry is different than the second gas chemistry, wherein the etching phase is performed in about 0.005 to 10 seconds for each cycle.

    摘要: Methods of depositing a protective coating of a silicon-containing or metallic material onto a semiconductor substrate include sputtering such material from an electrode onto a semiconductor substrate in a plasma processing chamber. The protective material can be deposited onto a multi-layer mask overlying a low-k material and/or onto the low-k material. The methods can be used in dual damascene processes to protect the mask and enhance etch selectivity, to protect the low-k material from carbon depletion during resist strip processes, and/or protect the low-k material from absorption of moisture.

    摘要: A temperature-controlled hot edge ring assembly adapted to surround a substrate support in a plasma reaction chamber. The assembly includes a conductive lower ring, a ceramic intermediate ring, and an upper ring. The intermediate ring overlies the lower ring and is adapted to be attached via the lower ring to an RF electrode. The upper ring overlies the intermediate ring, and has an upper surface exposed to an interior of a plasma reaction chamber.

    摘要: The present invention provides a plasma reactor having a plasma source chamber capable of generating a high density plasma typically utilizing a helicon wave. The plasma is delivered to a process chamber having a workpiece. The present invention may provide a plurality of magnets, each being located longitudinally around an axis perpendicular to the plane of the workpiece to form a magnetic bucket that extends the length of the side wall of the processing chamber and across a workpiece insertion opening and a vacuum pump opening. The magnetic bucket of the present invention may be formed so that the pedestal need not be raised to be within the bucket, or may be formed by permanent magnets oriented with one pole of each magnet facing the interior of the processing chamber, or with opposite poles of adjacent magnets facing each other, thereby forming cusps around the axis perpendicular to the plane of the workpiece. Current carrying conductors may generate all or part of the magnetic bucket. The present invention may provide an inner wall member secured within the processing chamber. All or a portion of the inner wall may be grounded to provide a well defined anode for bias power that is applied to the workpiece pedestal, and may be heated so that deposits do not cause its impedance to drift.
