  • Patent number: 12251735
    Abstract: A substrate is held in a horizontal attitude by a substrate holder. At a processing position, a lower surface of the substrate held by the substrate holder is cleaned by a lower-surface brush. The lower-surface brush is cleaned by a brush cleaner at a waiting position that overlaps with the substrate held by the substrate holder in an up-and-down direction and is below a processing position. The lower-surface brush is lifted and lowered by a lower-surface brush lifting-lowering driver between the processing position and the waiting position.

  • Publication number: 20250001462
    Abstract: A substrate cleaning device includes an upper holding device. The upper holding device holds a substrate in a horizontal attitude without rotating the substrate, while being in contact with an outer peripheral end of the substrate. A lower-surface brush wetted with a cleaning liquid is pressed against a lower-surface center region of the substrate held by the upper holding device. In this state, the lower-surface brush is rotated or moved with respect to the lower-surface center region of the substrate. Thus, the lower-surface center region of the substrate is cleaned.

  • Publication number: 20240321598
    Abstract: A substrate cleaning device includes a substrate holder, a lower-surface brush, a first liquid nozzle and a second liquid nozzle. The substrate holder holds a substrate in a horizontal attitude. The lower-surface brush is configured to be movable between a processing position for cleaning of the substrate and a waiting position that overlaps with the substrate held by the substrate holder in an up-and-down direction. Further, the lower-surface brush is configured to be rotatable about an axis extending in the up-and-down direction. The lower-surface brush cleans a lower surface of the substrate by coming into contact with the lower surface of the substrate. The first liquid nozzle discharges a cleaning liquid to a center portion of the lower-surface brush, at a waiting position. The second liquid nozzle discharges a cleaning liquid to an end portion of the lower-surface brush, at the waiting position.

  • Patent number: 12036583
    Abstract: A cleaner comes into contact with a lower-surface center region of a substrate held by a first holder, so that the lower-surface center region is cleaned. The cleaner comes into contact with a lower-surface outer region of the substrate rotated by a second holder, so that the lower-surface outer region of the substrate is cleaned. During cleaning of the lower-surface center region, the second holder is rotated about a vertical axis while not holding the substrate. Alternatively, during cleaning of the lower-surface center region, the gas injector arranged between the cleaner and the second holder injects gas toward the substrate from a first height spaced apart from the substrate by a predetermined distance. Further, during drying of the lower-surface center region, the gas injector injects gas toward the substrate from a second height closer to the substrate than the first height.

  • Publication number: 20230017418
    Abstract: An upper holding device holds a substrate in a horizontal attitude without rotating the substrate. A lower holding device rotates a substrate while holding the substrate by suction. A substrate held by the upper holding device is cleaned with use of a cleaning liquid, and a substrate held by the lower holding device is cleaned with use of a cleaning liquid. Gas in a processing space is exhausted by exhaust equipment of a factory through an exhaust system. When a substrate is held by the upper holding device, gas in the processing space is not exhausted or gas in the processing space is exhausted at a first flow rate. Gas in the processing space is exhausted at a second or third flow rate that is higher than the first flow rate when the substrate is held by the lower holding device.

  • Patent number: 11413798
    Abstract: A vehicle interior board which is thin, lightweight, has high strength, has less degradation, peeling and the like near an end portion of a metal plate, and has high quality and excellent productivity; and a method for manufacturing the same. The vehicle interior board includes a pair of metal plates and a foamed polyurethane layer formed between the pair of metal plates. A projecting ridge projecting outwardly and extending in a predetermined direction along the outer surface is formed on an outer surface of the metal plate. Thus, it is possible to obtain desired strength and rigidity even when the metal plates or the foamed polyurethane layer are thinned or when a lightweight aluminum plate or the like is adopted as the metal plates. Therefore, it is possible to reduce weight of a vehicle interior board.
