  • Patent number: 11000783
    Abstract: A chamber has a first opening, a second opening, and a third opening. The second opening is higher in level than the first and third openings, and is located at the highest position of a reservoir. Air bubbles are easily collected around the second opening, higher in level than the third opening, due to buoyancy. Moreover, the chamber includes an upper slope on an upper inner wall thereof such that a sectional area of the chamber becomes smaller toward the highest position of the reservoir. The upper slope causes the air bubbles not to stagnate but to be guided to the second opening along the upper slope. This makes easy discharge of the air bubbles from the chamber.

  • Patent number: 10920764
    Abstract: A chamber has at least three openings, or a first opening, a second opening, and a third opening formed therein that are in communication with a reservoir. The second opening is higher in level than the first opening. The third opening is used for discharging a liquid within the reservoir by introducing gas through at least one of the first opening and the second opening into the reservoir. Since the third opening is the lowest in level among the three openings, the liquid stored in the reservoir is able to be drained easily.

  • Patent number: 10824074
    Abstract: A development liquid is discharged from a development liquid nozzle having one discharge port extending continuously in one direction to the substrate. The development liquid nozzle is fixed such that the development liquid is supplied to a reference straight line on an upper surface of the substrate, and is fixed such that a liquid receiving region that receives the development liquid on the upper surface of the substrate extends in a direction inclined with respect to the reference straight line, the reference straight line passing through a rotational center of the substrate. The development liquid nozzle is moved in a direction of the reference straight line. The liquid receiving region has one end and another end. The other end is located farther away from the rotational center of the substrate than the one end, and is located farther downstream in the rotation direction of the substrate than the one end.

  • Patent number: 10818520
    Abstract: Disclosed is a substrate treating apparatus including a substrate holder, a rotating drive unit, a treatment liquid supplying unit, an exterior cup, and an interior cup. The interior cup is movable between a collection position where the interior cup collects the treatment liquid and a retracting position where the exterior cup collects the treatment liquid, and includes an interior cup main body with an annular contour, a liquid outlet in the interior cup main body for draining the treatment liquid in the interior cup main body, and an exhaust port in the interior cup main body for exhausting gas in the interior cup main body. The exterior cup includes an exterior cup main body with an annular contour, a liquid outlet in the exterior cup main body for draining the treatment liquid in the exterior cup main body, and an exhaust port in the exterior cup main body for exhausting gas in the exterior cup main body.

  • Patent number: 10790165
    Abstract: A drive mechanism deforms two diaphragms to perform alternate increase and decrease in volume of a supply chamber. At this time, the two diaphragms are provided for the single supply chamber. This leads to possibility of suction and feed out of a desired amount of liquid even with limited deformation of the diaphragms. In addition, the two diaphragms achieve suppression in deformation thereof upon suction and feed out of a desired amount of liquid. This allows selection of the diaphragms each with a short stroke, yielding suppressed stagnation and quality degradation of the liquid.

  • Patent number: 10627836
    Abstract: A pumping apparatus includes a pump chamber, a piston, a motor, and a controller. The controller determines an imaginary terminal point by referring to a dispense command, theoretical information, and a current position of the piston. The controller corrects the imaginary terminal point to a target position by referring to a correction graph. The controller outputs a drive command to the motor for moving the piston from a start position to the target position.

  • Patent number: 10507484
    Abstract: Provided is a pump apparatus, having an upstream pump, a filter, and a downstream pump being inserted into a processing liquid flow path in this order. The downstream pump has an inlet higher in level than an outlet of the upstream pump and higher in level than an outlet of the filter. That is, the downstream pump is disposed higher in level than the upstream pump and the filter. Accordingly, this allows a processing liquid to flow upward. Even when air bubbles are generated in the processing liquid, buoyancy causes the air bubbles to move upward in the processing liquid flow path and collect the air bubbles on a downstream side. Consequently, the air bubbles are readily vented from the processing liquid flow path.
