Abstract: A substrate processing apparatus includes a discharge part including a nozzle configured to discharge a processing liquid onto a substrate; a liquid feeder configured to feed the processing liquid to the discharge part; a replenishment part configured to replenish the liquid feeder with the processing liquid to be fed to the discharge part; a connector including a switching valve configured to open/close a flow path between the replenishment part and the liquid feeder; a filter configured to remove foreign matters contained in the processing liquid; a replenishment preparation part configured to open the switching valve after reducing a pressure difference between the inside of the replenishment part and the liquid feeder; and a replenishment controller configured to start replenishment of the processing liquid from the replenishment part to the liquid feeder in a state in which the switching valve is opened by the replenishment preparation part.

Abstract: A stay of a liquid can be suppressed. A pump 100 includes a tube 102, having elasticity, in which a liquid as a target to be delivered flows; a tube housing 104 which covers an outside of the tube 102 and keeps a gas in an inner space V between an outer surface of the tube 102 and the tube housing 104; and an electropneumatic regulator RE configured to supply the gas into the inner space V and discharge the gas from the inner space V.
Abstract translation: 可以抑制液体滞留。 泵100包括具有弹性的管102，其中作为待输送的靶的液体流动; 管壳体104，其覆盖管102的外部并将气体保持在管102的外表面和管壳体104之间的内部空间V中; 以及电气调节器RE，其构造成将气体供应到内部空间V并从内部空间V排出气体。

Abstract: A tank includes a container part having an upper wall, a sidewall and a bottom wall to store a processing liquid therein, a liquid discharge passage installed at a position higher than a liquid surface of the processing liquid stored in the container part to discharge the processing liquid into the container part, and a gas discharge passage installed at a position higher than the liquid surface to discharge a gas into the container part. The liquid discharge passage discharges the processing liquid from the liquid discharge port so that the processing liquid is brought into contact with a portion above the liquid surface of an inner surface of the sidewall. The gas discharge passage discharges the gas from the gas discharge port so that the gas is brought into contact with a portion above the liquid surface of an inner surface of the container part.
