  • Publication number: 20050178748
    Abstract: An overhead gas distribution electrode forming at least a portion of the ceiling of a plasma reactor has a bottom surface facing a processing zone of the reactor. The electrode includes a gas supply manifold for receiving process gas at a supply pressure at a top portion of the electrode and plural pressure-dropping cylindrical orifices extending axially relative to the electrode from the gas supply manifold at one end of each the orifice. A radial gas distribution manifold within the electrode extends radially across the electrode. Plural axially extending high conductance gas flow passages couple the opposite ends of respective ones of the plural pressure-dropping orifices to the radial gas distribution manifold. Plural high conductance cylindrical gas outlet holes are formed in the plasma-facing bottom surface of the electrode and extend axially to the radial gas distribution manifold.

  • Publication number: 20050106873
    Abstract: A method and apparatus for processing a semiconductor substrate is disclosed. A plasma reactor has a capacitive electrode driven by a plurality of RF power sources, and the electrode capacitance is matched at the desired plasma density and RF source frequency to the negative capacitance of the plasma, to provide an electrode plasma resonance supportive of a broad process window within which the plasma may be sustained.

  • Publication number: 20050001556
    Abstract: A plasma reactor includes a vacuum enclosure including a side wall and a ceiling defining a vacuum chamber, and a workpiece support within the chamber and facing the ceiling for supporting a planar workpiece, the workpiece support and the ceiling together defining a processing region between the workpiece support and the ceiling. Process gas inlets furnish a process gas into the chamber. A plasma source power electrode is connected to an RF power generator for capacitively coupling plasma source power into the chamber for maintaining a plasma within the chamber. The reactor further includes at least a first overhead solenoidal electromagnet adjacent the ceiling, the overhead solenoidal electromagnet, the ceiling, the side wall and the workpiece support being located along a common axis of symmetry.
