  • Publication number: 20230282493
    Abstract: A substrate processing system includes: a carry-in/out section in which a cassette accommodating a plurality of substrates is carried in/out; a batch processing section in which a wafer lot including the plurality of substrates is collectively processed in a state where each of the plurality of substrates stand upright; a single-wafer processing section in which the plurality of substrates included in the wafer lot are processed one by one in a horizontal state; and an interface section that delivers the plurality of substrates from the batch processing section to the single-wafer processing section. The interface section includes: a standby table that horizontally holds a substrate in a state of being in contact with pure water; and a transfer mechanism that delivers the substrate from the batch processing section to the standby table.

  • Publication number: 20230268202
    Abstract: A substrate processing system includes: a carry-in/out section in which a cassette accommodating a plurality of substrates is carried in/out; a batch processing section in which a wafer lot including the plurality of substrates is collectively processed; a single-wafer processing section in which the substrates of the wafer lot is processed one by one; and an interface section that delivers the substrates between the batch processing section and the single-wafer processing section. The batch processing section includes: a processing bath in which the wafer lot is immersed and processed; and a first transfer device that transfers the wafer lot to the processing bath. The interface section includes: an immersion bath disposed outside a movement range of the first transfer device and that immerses the wafer lot; and a second transfer device that holds and transfers the wafer lot between the first transfer device and the immersion bath.

  • Patent number: 11615971
    Abstract: There is provided a substrate processing apparatus including: a processing part configured to process a substrate with a processing liquid; and a processing liquid generation part configured to generate the processing liquid supplied to the processing part. The processing liquid generation part includes: a reservoir configured to store the processing liquid; a circulation line through which the processing liquid stored in the reservoir is circulated; a heater configured to heat the processing liquid; and a nozzle provided at a downstream side of the circulation line and has at least one ejection port formed to eject the processing liquid heated by the heater from above a liquid level of the processing liquid stored in the reservoir.

  • Publication number: 20210366740
    Abstract: A substrate processing apparatus includes: a processing container, a mixing device, a liquid feeding path, and a controller. The processing container processes a substrate by immersing the substrate in a processing liquid. The mixing device mixes a phosphoric acid aqueous solution and an additive, to produce a mixed liquid to be used as a raw material of the processing liquid. The liquid feeding path feeds the mixed liquid from the mixing device to the processing container. The controller controls the substrate processing apparatus. The controller performs a control to feed the mixed liquid from the mixing device to the processing container in which the substrate is immersed, after a phosphoric acid concentration of the mixed liquid is regulated from a first concentration to a second concentration higher than the first concentration. The first concentration is a concentration when the phosphoric acid aqueous solution is supplied to the mixing device.

  • Publication number: 20210368586
    Abstract: A storage device according to an aspect of the present disclosure includes a storage tank, a heating mechanism, and a controller. The storage tank stores a processing liquid that contains an aqueous solution of phosphoric acid and an additive. The heating mechanism heats the processing liquid that is stored in the storage tank. The controller controls the heating mechanism to execute a concentration maintaining process where a temperature of the processing liquid is adjusted in such a manner that an amount of evaporation of water for the processing liquid in the storage tank approaches an amount of absorption of moisture for the processing liquid in the storage tank.
