  • Publication number: 20240075410
    Abstract: There is provided a gas solution supply apparatus capable of preventing bubbles from being generated in use at a point-of-use even if gas solution to be provided to a point-of-use has a high concentration. The gas solution supply apparatus 1 includes: a gas dissolving unit 4 that dissolves a source gas in a source liquid to produce a first gas solution; a first gas-liquid separator 10 that stores the first gas solution produced and produces a second gas solution through gas-liquid separation of the first gas solution; a pressure reducer 17 that depressurizes the second gas solution produced in the first gas-liquid separator 10; and a second gas-liquid separator 12 that stores the depressurized second gas solution and produces a third gas solution through gas-liquid separation of the second gas solution. The third gas solution is supplied to a point-of-use.

  • Patent number: 10633757
    Abstract: There are provided a plating apparatus and a plating method that allow determining an appropriate replacement timing of a diaphragm. The plating apparatus includes an anode bath, a cathode bath, a diaphragm, an analyzer, and a control device. The anode bath holds a plating solution and an insoluble anode. The cathode bath holds a plating solution containing an additive and a substrate. The diaphragm separates the plating solution held in the anode bath from the plating solution held in the cathode bath. The analyzer is configured to analyze a concentration of the additive in the plating solution in the cathode bath at every predetermined time interval. The control device is configured to calculate an actual consumption of the additive during the predetermined period based on the concentration of the additive analyzed at the every predetermined time interval. The control device includes a memory that stores an expected consumption of the additive during the predetermined period.
