  • Patent number: 11353894
    Abstract: A liquid processing apparatus includes: a substrate processing unit; a supply line that supplies the fluid to the substrate processing unit; a flow meter that measures a flow rate of the fluid flowing through the supply line; a flow rate adjustment mechanism that adjusts the flow rate of the fluid flowing through the supply line; and a controller that control the flow rate adjustment mechanism based on a measurement result of the flow meter. The controller receives the measurement result at a first cycle. When the measurement result of the flow meter indicates that the flow rate of the fluid flowing through the supply line is included in a preset range, the controller causes the flow rate adjustment mechanism to adjust the flow rate of the fluid flowing through the supply line at a cycle having a time interval longer than a time interval of the first cycle.

  • Patent number: 11135698
    Abstract: Disclosed is a processing apparatus that includes a chamber accommodating a workpiece, a nozzle provided within the chamber, a measuring unit measuring the supply flow rate of the processing fluid supplied to the nozzle, an opening/closing unit performing opening/closing of the flow path of the processing fluid, and a controller. The controller sends an opening/closing operation signal that causes the opening/closing unit to perform an opening/closing operation according to recipe information that indicates processing contents. After sending the opening/closing operation signal to the opening/closing unit according to the recipe information, the controller starts the integration of the supply flow rate based on the measurement result of the measuring unit, monitors the rise of the supply flow rate based on the calculated integrated amount, and when supplying a specific flow rate, monitors the supply flow rate based on a value actually measured by the measuring unit.

  • Patent number: 11043399
    Abstract: A plasma processing apparatus includes a storage; processors; a liquid supply which supplies, into the storage, at least a first liquid composed of a processing liquid or source liquids for composing the processing liquid; a detector which detects a value of a parameter indicating a state of the first liquid supplied into the storage or a state of the processing liquid in the storage; and a controller which controls the processors to perform a liquid processing in sequence. The controller determines, based on a detection result of the value of the parameter, whether it is possible to supply the processing liquid continuously into a preset number of processors concurrently under a condition requested by the processors, and, if not, the controller performs a simultaneous processing restricting control of reducing a number of processors which are supposed to perform the liquid processing concurrently to be lower than the preset number.

  • Patent number: 10261521
    Abstract: Disclosed is a processing apparatus including a chamber, at least one nozzle, a measuring unit, an opening/closing unit, and a controller. The chamber accommodates a workpiece therein. The nozzle is provided in the chamber to supply a processing fluid toward the workpiece. The measuring unit measures a supply flow rate of the processing fluid supplied to the nozzle. The opening/closing unit performs opening/closing of a flow path of the processing fluid to be supplied to the nozzle. The controller outputs opening and closing operation signals at a preset timing. After outputting the opening operation signal, the controller calculates an integrated amount of the processing fluid based on a measurement result of the measuring unit, and performs an output timing change processing to change a timing of outputting the opening or closing operation signal from the preset timing based on the calculated integrated amount.

  • Patent number: 8409359
    Abstract: Disclosed is a substrate processing apparatus capable of decreasing the frequency of shutdown of the apparatus due to lack of processing liquid in a processing liquid supply unit, as well as efficiently using the processing liquid to improve a yield ratio. The substrate processing apparatus includes a plurality of liquid processing units to conduct liquid processing of substrates a substrate carrying unit to carry the substrates in and out of the liquid processing units, a processing liquid supply unit to supply the liquid processing units with processing liquid, and a level gauge to detect an amount of the processing liquid remaining in the processing liquid reservoir of the processing liquid supply unit. The carry of the substrates in the liquid processing units is suspended when the level gauge detects that the amount of the processing liquid remaining in the processing liquid reservoir is below a predetermined threshold.
