  • Publication number: 20220402003
    Abstract: The disclosure provides a substrate cleaning device and a substrate processing device capable of suppressing erroneous rotation detection of an optical sensor due to adhesion of droplets or mist. A substrate cleaning device includes a substrate cleaning part for cleaning a substrate, a drive roller for rotating the substrate, a driven roller rotated by the substrate, and a rotation detection part for detecting rotation of the driven roller. The rotation detection part includes a detected part provided on the driven roller, an optical sensor for detecting rotation of the detected part by irradiation with detection light, and a liquid filling part for filling an optical path forming space in which an optical path of the detection light is formed with a liquid having transmittance.

  • Patent number: 10589398
    Abstract: A heat exchanger which can allow a surface temperature of a polishing pad to promptly reach a target temperature and can realize a uniform distribution of the surface temperature of the polishing pad is disclosed. The heat exchanger includes a pad contact surface capable of contacting the polishing pad, a heating flow passage through which a heating fluid is to flow, and a cooling flow passage through which a cooling fluid is to flow. The heating flow passage and the cooling flow passage are arranged side by side from beginnings to ends thereof, and the heating flow passage and the cooling flow passage cross each other at different levels at a peripheral portion of the pad contact surface.

  • Patent number: 10475691
    Abstract: A substrate transfer hand is configured to sandwich a substrate between a plurality of receiving members and a gripping member and to fix the substrate by moving the gripping member with an actuator. The plurality of receiving members each have a flat plate-shaped support portion mounted on the main hand body, a substrate outer periphery holding portion supported on the support portion and configured to hold an outer periphery of the substrate, and a substrate lower surface holding portion supported on the support portion and configured to hold a lower surface of the substrate. The substrate outer periphery holding portion has a portion provided vertically from the support portion and configured to hold the substrate in contact with the outer periphery of the substrate. The substrate lower surface holding portion has a portion inclined from an outer peripheral side toward an inner side of the substrate to be held.
