Koji Hashizume 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: 8268113
    Abstract: A bonded-substrate fabricating apparatus capable of reducing defective bonded substrates fabricated. A transfer robot sucks the outer edge area of the bottom surface of a substrate and spouts gas toward the bottom surface of the substrate to carry the substrate into a vacuum process chamber of a press machine while keeping the substrate horizontally. A press plate holds the substrate, which is held by the transfer robot, by suction.
    Type: Grant

  • Patent number: 8128768
    Abstract: The present invention provide an apparatus for manufacturing a bonded substrate that suppresses a defect in the bonded substrate. When the pressure in a vacuum chamber is at the atmospheric level, upper and lower chuck units respectively attract substrates through vacuum. When the vacuum chamber is depressurized, each chuck unit electrostatically attracts the associated substrate. During the depressurization of the vacuum chamber, the pressure for attracting each substrate to the associated chuck unit is controlled to be equal to the pressure in the vacuum chamber. This prevents each substrate from falling from or moving relative to the associated chuck unit. The first and second substrates are thus bonded together as accurately aligned.
