  • Patent number: 8221553
    Abstract: A method for producing an organic light-emitting device is provided for an organic light-emitting device having a substrate provided with external connection terminals, organic light-emitting elements provided on the substrate, and a protective film that covers the organic light-emitting elements. The method includes, sequentially, providing a protective film removal layer on the external connection terminals, forming the protective film on the substrate, dividing the substrate on which the protective film has been formed, and cleaning the substrate with water, an aqueous solution, or a solvent. The protective film removal layer and the protective film are removed from the external connection terminals as a result of cleaning the substrate.

  • Patent number: 7587989
    Abstract: In a plasma processing method, on a back side of a cathode electrode is provided at least one conductor plate d.c. potentially insulated from the cathode electrode and an opposing electrode, and the cathode electrode and the conductor plate are enclosed with a shielding wall such that a ratio of an inter-electrode coupling capacitance provided by the cathode electrode and the opposing electrode to a coupling capacitance provided by the cathode electrode and a bottom surface of the shielding wall on the back side of the conductor plate is not less than a predetermined value. Thereby, a high-quality, high-speed plasma processing is realized.

  • Publication number: 20090145555
    Abstract: There is disclosed an exhaust processing process of a processing apparatus for processing a substrate or a film, which comprises after the processing of the substrate or the film, introducing a non-reacted gas and/or a by-product into a trap means comprising a filament comprised of a high-melting metal material comprising as a main component at least one of tungsten, molybdenum and rhenium; and processing the non-reacted gas and/or the by-product inside the trap means. This makes it possible to prevent lowering in exhaust conductance, to lengthen the maintenance cycle of the processing apparatus, and to provide a high-quality product (processed substrate or film).
