    Abstract: A two-step process is disclosed for stripping photoresist material from a substrate, wherein the substrate includes a low k dielectric material underlying the photoresist material and a polymer film overlying both the photoresist material and the low k dielectric material. The first step of the two-step process uses an oxygen plasma to remove the polymer film. The second step of the two-step process uses an ammonia plasma to remove the photoresist material, wherein the second step commences after completion of the first step. Each step of the two-step photoresist stripping process is respectively defined by particular values for process parameters including chemistry, temperature, pressure, gas flow rate, radio frequency power and frequency, and duration.

    Abstract: A gas distribution system for supplying different gas compositions to a chamber, such as a plasma processing chamber of a plasma processing apparatus is provided. The gas distribution system can include a gas supply section, a flow control section and a switching section. The gas supply section provides first and second gases, typically gas mixtures, to the flow control section, which controls the flows of the first and second gases to the chamber. The chamber can include multiple zones, and the flow control section can supply the first and second gases to the multiple zones at desired flow ratios of the gases. The gas distribution system can continuously supply the first and second gases to the switching section and the switching section is operable to switch the flows of the first and second gases, such that one of the first and second process gases is supplied to the chamber while the other of the first and second gases is supplied to a by-pass line, and then to switch the gas flows. The switching section preferably includes fast switching valves operable to quickly open and close to allow fast switching of the first and second gases, preferably without the occurrence of undesirable pressure surges or flow instabilities in the flow of either gas.

    Abstract: A chamber includes a lower electrode and an upper electrode. The lower electrode is defined to transmit a radiofrequency current through the chamber and to support a semiconductor wafer in exposure to a plasma within the chamber. The upper electrode is disposed above and in a spaced apart relationship with the lower electrode. The upper electrode is electrically isolated from the chamber and is defined by a central section and one or more annular sections disposed concentrically outside the central section. Adjacent sections of the upper electrode are electrically separated from each other by a dielectric material. Multiple voltage sources are respectively connected to the upper electrode sections. Each voltage source is defined to control an electric potential of the upper electrode section to which it is connected, relative to the chamber. The electric potential of each upper electrode section influences an electric potential of the plasma within the chamber.
