  • Patent number: 7282105
    Abstract: Miniature planar IR waveguides of thickness 30–50 ?m, consisting of 12-mm long, 2-mm wide strips of Ge supported on ZnS substrates and tapered quasi-tapered waveguides, tapered from a thickness of 1 mm at the ends to a minimum of 1–100 ?m at the center, are disclosed. The surface sensitivity is increased as a function of incidence or bevel angle. The tapered waveguide improves the efficiency of the optical coupling both into the waveguide from an FTIR spectrometer, and out of the waveguide onto a small-area IR detector. The tapering makes it possible to dispense with using an IR microscope couple light through the waveguide, enabling efficient coupling with a detector directly coupled to an immersion lens. This optical arrangement makes such thin supported waveguides more useful as sensors, because they can be made quite long (e.g. 50 mm) and mounted horizontally.

  • Patent number: 6949158
    Abstract: A method and apparatus are disclosed for mounting a wafer on a mount and thinning the wafer. The wafer includes a front surface having bumps with an adhesive tape having a backing attached thereto and a back surface. The front surface of the wafer is mounted facedown on a suction surface with the backing of the adhesive tape abutting the surface. The wafer is then suctioned, after which the back surface of the wafer undergoes a grinding process to thin the wafer. Since the backing attached to the bumps on the wafer is substantially planar and sits substantially flat on the suction surface of the wafer mount, the force exerted on the wafer from the thinning process does not overcome the suction force holding the wafer on the wafer mount. Thus, the bumped wafer may be thinned without damaging the bumps and the active surface of the wafer.

  • Patent number: 6551440
    Abstract: An object of the invention is to prolong the seal life of a color EL display apparatus. The initial thickness of a light-transmitting main substrate is larger than a predetermined reference thickness WC. First, a plurality of thin-film EL devices are formed on one surface of the main substrate. Then, a sealing substrate having a concave portion formed in one surface thereof is bonded onto the one surface of the main substrate at predetermined intervals. Then, a protective material for protecting the thin-film EL devices is filled in the gap between the one surface of the main substrate and the sealing substrate. Then, the main substrate is processed so as to have the reference thickness WC. Then, a color filter portion is formed on the other surface of the main substrate. Lastly, a reinforcing substrate is attached to the other surface of the main substrate with the color filter portion in between.

  • Publication number: 20030047269
    Abstract: A method of manufacturing circuit board comprising: holding a laminate with metal foil or resin-coated metal foil disposed on both surfaces or on one surface of board material or board material with metal foil circuit formed thereon between metal plates, and applying at least one of heat and pressure to the laminate. A hard coat layer formed on both surfaces or on one surface of the metal plate protects the metal plate. Accordingly, the metal plate is hardly scratched by its contact with the conveyor and the like or by handling by the operator during the production of the circuit boards. Further, since the hard coat layer surface is smoothly finished, resin or contamination sticking to the metal plate can be easily removed, thereby prolonging the life of the metal plate. As a result, it is possible to produce high-quality circuit boards at low costs.

  • Patent number: 6491852
    Abstract: A method of making terrazzo floors with design inlays. The method utilizes pre-molded inserts as inlays in the finished floor, and generally includes four steps. First, inserts are pre-molded, which has design elements in terms of their color, nature of inclusions (chips, glass fragments, etc. and their colors), shape and/or a pattern of grooves in their upper surfaces. Second, the pre-molded inserts are placed on and affixed to the sub-flooring in a predetermined arrangement. Third, epoxy flooring mixture is poured to a height that fills the grooves in the inserts' upper surfaces and preferably cover the inserts. Fourth, the floor, after cured and hardened, is ground and polished to expose the upper surfaces of the inserts, which now become seamlessly integrated inlays within the overall finished floor.
