Patents by Inventor Yutaka IKEGAMI

Yutaka IKEGAMI 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: 11839893
    Abstract: A holding mechanism holds a substrate horizontally. A rotation mechanism rotates the holding mechanism holding the substrate. A nozzle supplies a processing liquid to the substrate. A nozzle arm holds the nozzle. An arm actuation mechanism moves the nozzle arm between a processing position overlapping the substrate in plan view and a retracted position displaced from the substrate in plan view. A cup portion is disposed around the holding mechanism, and receives the processing liquid from the substrate. A cup actuation mechanism moves the cup portion up and down between an upper position and a lower position. A first container is fixed to the cup portion to be movable up and down integrally with the cup portion, and can accommodate the nozzle at the retracted position.

  • Publication number: 20220415697
    Abstract: The substrate processing apparatus includes a suction holding mechanism, a rotation mechanism, a plurality of lift pins, a vertical movement mechanism, and a horizontal movement mechanism. The suction holding mechanism sucks and holds a substrate. The rotation mechanism rotates the suction holding mechanism holding the substrate about the rotation axis. The vertical movement mechanism moves the plurality of lift pins in the vertical direction. A sensor measures the eccentric state of the substrate W held by the suction holding mechanism. The vertical movement mechanism supports the substrate from the suction holding mechanism by moving the plurality of lift pins and the horizontal movement mechanism moves the plurality of lift pins based on the eccentric state of the substrate measured by the sensor in a state where the substrate is supported.
