Abstract: A substrate processing apparatus includes a plurality of processing units, an exhaust route, a gas processing device, and a controller. The exhaust route is provided where a gas that is discharged from the plurality of processing units. The gas processing device eliminates a target component in the gas and includes a duct, a partition plate, a liquid supply unit, and a concentration detection unit. The duct has a flow path. The partition plate partitions the flow path into a plurality of spaces and is formed of a porous material. The liquid supply unit supplies a dissolving liquid to the partition plate. The concentration detection unit detects a concentration of the target component. The controller regulates a flow volume of the dissolving liquid, based on at least one of operation information that indicates operation states of the plurality of processing units and a detection result of the concentration detection unit.

Abstract: A gas processing apparatus includes a duct, a partition plate and a liquid supply. The duct has therein a flow path through which a gas passes. The partition plate is configured to divide the flow path into multiple spaces, and is formed of a porous material, through which the gas passes, configured to retain a liquid. The liquid supply is configured to supply a dissolving liquid configured to dissolve a target component contained in the gas to the partition plate. The gas passing through the flow path is brought into contact with the dissolving liquid retained in the partition plate.

Abstract: A substrate processing apparatus includes processing units, an exhaust path, a gas processing apparatus and a controller. Each processing unit is configured to process a substrate by using a chemical. A gas exhausted from the processing units flows through the exhaust path. The gas processing apparatus is provided in the exhaust path to remove a target component contained in the gas. The gas processing apparatus includes a duct, a partition plate and a liquid supply. The duct has therein a flow path. The partition plate divides the flow path into spaces, and is formed of a porous material, through which the gas passes, configured to retain a liquid. The liquid supply is configured to supply a dissolving liquid configured to dissolve the target component to the partition plate. The controller adjusts a flow rate of the dissolving liquid according to operation information indicating an operational status of the processing units.

Abstract: A substrate liquid processing apparatus includes a liquid unit configured to process a liquid processing unit configured to process a substrate with multiple kinds of processing liquids, an exhaust pipe connected to the liquid processing unit, and configured to allow an exhaust gas from the liquid processing unit to flow therein, a plurality of individual exhaust pipes provided to correspond to at least one of the multiple kinds of processing liquids, and an exhaust switching unit connected to the exhaust pipe and the individual exhaust pipes, and configured to change a discharge destination of the exhaust gas flowing within the exhaust pipe to one of the individual exhaust pipes. The exhaust switching unit is positioned above the liquid processing unit.

Abstract: Disclosed is a substrate processing apparatus including a chamber, a first measuring unit, an exhaust pipe, a regulation valve, an opening degree detection unit, a valve controller, and a clogging detection unit. The chamber accommodates therein a substrate to be processed by using a processing fluid. The first measuring unit measures an internal pressure of the chamber. An exhaust from the chamber flows through the exhaust pipe. The regulation valve regulates an exhaust volume of the exhaust pipe. The opening degree detection unit detects a valve opening degree of the regulation valve. The valve controller controls the valve opening degree of the regulation valve based on a measurement result of the first measuring unit to keep the internal pressure within a specified range. The clogging detection unit detects clogging of the exhaust pipe based on the valve opening degree detected by the opening degree detection unit.
