Yoshitaka Abiko has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8043468
    Abstract: A substrate processing apparatus discharges a hydrofluoric acid solution from discharge nozzles toward grooves formed in side walls of an inner bath. The hydrofluoric acid solution discharged from the discharge nozzles impinges upon the grooves to diffuse, thereby moving toward a top portion of the inner bath in the form of low-speed uniform liquid flows. Thus, a metal component and foreign substances generated in the inner bath float up toward the top portion of the inner bath without being agitated within the inner bath, and are rapidly drained to an outer bath together with the hydrofluoric acid solution.
    Type: Grant

    Date of Patent: October 25, 2011

  • Patent number: 7541285
    Abstract: A substrate processing apparatus performs a chemical solution process in a chemical solution process room that is partially formed within a chamber. During the chemical solution process, the substrate processing apparatus seals the chemical solution process room, and measures the pressure within the chemical solution process room, and controls the pressure within the chemical solution process room, based on a measured value. Irrespective of location environment of the substrate processing apparatus, the chemical solution process room can be controlled to a predetermined pressure. The substrate processing apparatus also permits efficient pressure control with respect to a minimum required amount of region.

  • Patent number: 7422681
    Abstract: A substrate treating apparatus for treating substrates having a film coating. The apparatus includes a treating unit for treating the substrates with a treating solution, a drain pipe for draining the treating solution from the treating unit, a filter mounted on the drain pipe, and an ultraviolet emitting unit for the filter for emitting ultraviolet light to the treating solution flowing through the filter.

  • Patent number: 7243911
    Abstract: A substrate treating apparatus for performing a predetermined treatment of substrates includes a treating tank for storing a treating solution, a holder for holding a plurality of substrates arranged in one direction inside the treating tank, and a bubble generating device for generating bubbles in the treating solution stored in the treating tank. The bubble generating device includes a plurality of cylindrical bodies extending in the one direction and arranged in a direction perpendicular to the one direction. Each of the cylindrical bodies is at least partly formed of a porous member extending in the one direction.

  • Publication number: 20060213542
    Abstract: A plurality of substrates after subjected to a chemical solution processing in a second processing bath is immersed in deionized water stored in a first processing bath. At this time, a holding mechanism is moved down such that the positions in the height direction of two holding bars among three holding bars, which are disposed on a deionized water nozzle side, are substantially the same as that of an upper deionized water nozzle. A lower deionized water nozzle keeps supplying deionized water, so that deionized water overflows an internal bath toward an external bath. Subsequently, to the two holding bars, the corresponding upper deionized water nozzles expel deionized water. This applies a sufficiently strong steam of water to the two holding bars, so that a residue adhered to holding grooves of these holding bars can be cleaned well. A holding groove of the rest holding bar can be cleaned well by a stream of water that can be formed by deionized water supplied from a lower deionized nozzle.
