  • 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.

  • Publication number: 20230001456
    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: 20220395866
    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.

  • Patent number: 10835932
    Abstract: It is an object to prevent adhesion of a processing liquid to a non-processing region of a substrate. In order to achieve the object, a substrate processing apparatus includes a substrate rotating mechanism, a discharging portion for discharging a processing liquid to a substrate, a moving portion for moving a discharging portion, and a controller. The discharging portion starts to discharge the processing liquid at a first position and is moved to a second position. The first position is a position of the discharging portion where a section of a passage of the discharging portion is projected onto a first region, and the second position is a position of the discharging portion where the section of the passage is projected onto a second region. The first region is a region on the peripheral edge side of the substrate from the second region.

  • Patent number: 10685856
    Abstract: While a substrate is being rotated, the lower surface of a brush is moved along the upper surface of the substrate. The brush and a spray nozzle are moved upward from a takeoff position to a lower non-contact position so as to separate the lower surface of the brush from the upper surface of the substrate. The spray nozzle generates the droplets in a state where the brush and the spray nozzle are located in the lower non-contact position so as to make the droplets collide with the upper surface of the substrate, and then the droplets colliding with the upper surface of the substrate are discharged from a gap between the lower surface of the brush and the upper surface of the substrate while the droplets are being supplied to the lower surface of the brush.

    Abstract: In parallel with a lower-side scrub cleaning step where a brush is contacted with a lower surface inclined portion of a substrate, a center-side spray cleaning step is performed where a collision position of liquid droplets with respect to an upper surface of the substrate is moved between the center of the substrate and the middle of the substrate while the liquid droplets collide with the upper surface of the substrate. Thereafter, in parallel with an upper-side scrub cleaning step where the brush is contacted with an upper surface inclined portion of the substrate, an outer circumference-side spray cleaning step is performed where the collision position of the liquid droplets with respect to the upper surface of the substrate is moved between the middle of the substrate and the outer circumference of the substrate while the liquid droplets collide with the upper surface of the substrate.
