  • Patent number: 7563477
    Abstract: In a method for fabricating an organic electroluminescent display, a first electrode layer is formed on a transparent substrate, and a hole transport layer is formed on the first electrode layer. After an organic luminescent layer is formed on the hole transport layer by scanning a donor film disposed on the substrate using a laser beam, the donor film is removed and then a second electrode is formed on the organic luminescent layer. The laser beam dithers while performing the scanning operation to make the energy distribution uniform.

  • Patent number: 7547466
    Abstract: One aspect of the present invention relates to a spindle motor manufacturing method for forming an oil repellent film which prevents a lubricating oil from flowing out, on a predetermined area adjacent to a hydrodynamic bearing, the predetermined area being located on at least one of a stationary member and a rotating member. The spindle motor manufacturing method mentioned above comprises a step of supplying an oil repellent solution by a supplying portion onto a part of the predetermined area for forming the oil repellent film, a step of applying an air current to the part of the predetermined area on which the oil repellent solution is supplied so as to peel off an excess part of the oil repellent solution supplied onto the part of the predetermined area, and a step of making a relative movement of the predetermined area in which the oil repellent film is formed, the relative movement being made with respect to the supplying portion by which the oil repellent solution is supplied.

  • Patent number: 7541067
    Abstract: A deposition method which deposits a CdS buffer layer on a surface of a solar cell from a process solution including all chemical components of the CdS buffer layer material. CdS is deposited in a deposition chamber by heating the surface of the solar cell absorber to cause the transfer of heat from the solar cell absorber layer to at least a portion of the process solution that is in contact with the surface. Used solution is cooled, and replenished in a solution container and redirected into the deposition chamber.

  • Patent number: 7455884
    Abstract: A method for atomic layer deposition providing a dispenser unit used to prevent mixing of a precursor gas and an input gas. From the dispenser unit a flow of the input gas is provided over a surface of the workpiece wherein a beam of the electromagnetic radiation is directed into the input gas in close proximity to the surface of the workpiece, but spaced a finite distance therefrom. The input gas is dissociated by the beam producing a high flux point of use generated reactive gas species that reacts with a surface reactant formed on the surface of the workpiece by a direct flow of the precursor gas flown from the dispensing unit. The surface reactant and reactive gas species react to form a desired monolayer of a material on the surface of the workpiece.
