  • Publication number: 20080014825
    Abstract: A vacuum deposition apparatus capable of enhancing the productivity of an organic electroluminescence device is realized. A first pipe is connected to a deposition source for evaporating an organic electroluminescence material, and two second pipes are directed to two film deposition objects comprised of substrates and masks, whereby an organic deposition film is formed. Vapor is released simultaneously from the deposition source to plural film deposition objects on different planes to deposit films, which promotes the reduction in film deposition time and the miniaturization of an apparatus.

  • Publication number: 20070221131
    Abstract: An object of the present invention is to reduce splash generated in a vapor deposition source and carry out vapor deposition at a stable, high vapor deposition speed. The vapor deposition according to the present invention is carried out by vertically stacking a plurality of doughnut-shaped flat plates in a crucible, mounting thin vapor deposition material on the doughnut-shaped flat plates, using heaters that surround the crucible to heat the vapor deposition material on the doughnut-shaped flat plates, allowing the vapor generated from the vapor deposition material to flow through a flow space A at each layer into a vertical flow path B, and discharging the vapor from an opening at the top of the flow path B toward a substrate to be deposited. The conductance of the flow space A is smaller than the conductance of the flow path B.

  • Patent number: 6500352
    Abstract: An electrode plate is formed by a substrate and a plurality of patterned electrodes formed on the substrate. Each patterned electrode has a laminate structure including a first layer of nickel metal formed on the substrate and a second layer of copper formed thereon. The electrode plate may be prepared by a process including a step of etching such a multi-layer metal electrode-forming film formed on a substrate by spraying an etchant downwardly and uniformly onto the substrate while rotating the substrate at a rotation speed sufficient to allow quick liberation of the etchant from the substrate. The metal electrodes can be formed with good adhesion onto the substrate and with good width and thickness accuracy. By incorporating the electrode plate as a pair of substrates sandwiching a liquid crystal, a liquid crystal device free from transmission delay and rounding of voltage waveforms can be provided.
