  • 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.

    Abstract: A substrate alignment device includes first and second support members that are arranged to be opposite to each other and be spaced apart from each other in a plan view, and respectively support an outer peripheral end of a substrate from a position below the substrate. Further, the substrate alignment device includes a first pressing member that is arranged to be opposite to the first support member in a plan view, and moves the substrate by pressing one portion of the outer peripheral end of the substrate in a first direction directed from the second support member toward the first support member with the substrate supported by the first and second support members. The first support member includes a movement limiter that limits movement of the substrate in the first direction past a predetermined prescribed position.
