Abstract: A substrate processing apparatus includes: a reservoir configured to temporarily store a processing liquid for processing a substrate; a replenisher configured to replenish the processing liquid to the reservoir; a flow rate measurer configured to measure a flow rate of the processing liquid replenished to the reservoir; a gas supplier configured to supply gas to the reservoir to pressurize an interior of the reservoir; and a controller, wherein the controller is configured to control the gas supplier based on a value measured by the flow rate measurer to execute a process of replenishing the processing liquid from the replenisher to the reservoir while regulating a magnitude of an internal pressure of the reservoir.

Abstract: A substrate processing apparatus according to the present disclosure includes a substrate holding unit, a fluid supplying unit, a processing-liquid supplying unit, a nozzle, a fluid amount adjusting unit, and a controller. The substrate holding unit holds a substrate to be rotatable. The fluid supplying unit supplies fluid including pressurized vapor or mist of deionized water. The processing-liquid supplying unit supplies processing liquid including at least a sulfuric acid. The nozzle is connected to the fluid supplying unit and the processing-liquid supplying unit to discharge mixed fluid of the fluid and the processing liquid toward the substrate. The fluid amount adjusting unit adjusts a flow volume of the fluid that is flowing through the fluid supplying unit. The controller controls the fluid amount adjusting unit to adjust a ratio of the fluid to the processing liquid.

Abstract: A liquid supply device includes: a storage tank configured to store a processing liquid including a first processing liquid (sulfuric acid) and a second processing liquid (hydrogen peroxide solution); a circulation path having a first pipeline through which the processing liquid passes in a horizontal direction, and configured to circulate the processing liquid stored in the storage tank; a branch path configured to supply the processing liquid to a processing unit; and a branching part having an opening for allowing the processing liquid to flow out from the first pipeline to the branch path, wherein the opening is formed in the branching part and formed below a periphery of the first pipeline when the first pipeline is viewed in section.

Abstract: A recovery route returns, to a retaining tank, mixed solution supplied to a substrate processing unit. A discarding route discards the supplied mixed solution to a place other than the retaining tank. A switching controller causes the supplied mixed solution to flow into the discarding route during a time interval until a first time interval has elapsed from a time point when the substrate processing unit starts to supply the mixed solution; causes the supplied mixed solution to flow into the recovery route during a time interval until a second time interval, which is decided based on a predetermined recovery rate, has elapsed after the first time interval elapses; and causes the supplied mixed solution to flow into the discarding route during a time interval until supply of the mixed solution has been ended from a time point when the second time interval elapses.
