    摘要: A plasma processing chamber having a lowered flow equalizer and a lower chamber liner. In an etching process, the processing gases may be unevenly drawn from the processing chamber which may cause an uneven etching of the substrate. By equalizing the flow of the processing gases evacuated from the chamber, a more uniform etching may occur. By electrically coupling the flow equalizer to the chamber liners, the RF return path from the flow equalizer may run along the chamber liners and hence, reduce the amount of plasma drawn below the substrate during processing.

    摘要: An apparatus for controlling thermal uniformity of a substrate-facing surface of a showerhead is provided herein. In some embodiments, the thermal uniformity of the substrate facing surface of the showerhead may be controlled to be more uniform. In some embodiments, the thermal uniformity of the substrate facing surface of the showerhead may be controlled to be non-uniform in a desired pattern. In some embodiments, an apparatus for controlling thermal uniformity of a substrate-facing surface of a showerhead may include a showerhead having a substrate facing surface and one or more plenums for providing one or more process gases through a plurality of gas distribution holes formed through the substrate facing surface of the showerhead; and a plurality of flow paths having a substantially equivalent fluid conductance disposed within the showerhead to flow a heat transfer fluid.

    摘要: A method and apparatus for controlling plasma uniformity is disclosed. When etching a substrate, a non-uniform plasma may lead to uneven etching of the substrate. Impedance circuits may alleviate the uneven plasma to permit more uniform etching. The impedance circuits may be disposed between the chamber wall and ground, the showerhead and ground, and the cathode can and ground. The impedance circuits may comprise one or more of an inductor and a capacitor. The inductance of the inductor and the capacitance of the capacitor may be predetermined to ensure the plasma is uniform. Additionally, the inductance and capacitance may be adjusted during processing or between processing steps to suit the needs of the particular process.
