  • Publication number: 20170043287
    Abstract: According to an embodiment of the present disclosure, a process liquid supply apparatus operating method is provided. The method includes filling a filter unit with a process liquid from an upstream side of the filter unit to a downstream side of the filter unit after newly mounting or replacing the filter unit and repeating a depressurization filtering process and a pressurization filtering process for a predetermined number of times. The depressurization filtering process depressurizes the process liquid in the downstream side of the filter unit and thereby allows the process liquid to permeate through the filter unit. The pressurization filtering process pressurizes the process liquid from the upstream side of the filter unit and thereby allows the process liquid to permeate through the filter unit.

  • Publication number: 20160236124
    Abstract: In one embodiment, after a new filter unit (3) is installed in a treatment liquid supply apparatus, there is performed, before a solvent-containing treatment liquid is passed through the filter unit, a step of soaking the filter unit with a solvent for pretreatment and then discharging therefrom the solvent. The solubility of a material, constituting a filter part (31) of the filter unit, to the solvent is greater than the solubility of the material to the treatment liquid. This step makes it possible to remove a component, which may elute from the filter part into the treatment liquid to produce foreign matters (particles), before treatment liquid is passed through the filter unit.

  • Publication number: 20150125793
    Abstract: A processing liquid supplying apparatus performs an ejecting step in which a processing liquid suctioned into a pump passes through a filter device and is ejected from an ejecting part without returning the processing liquid back to the pump; a returning step in which the processing liquid suctioned into the pump is returned to a processing liquid source side of a mixing section; and a replenishing step in which the processing liquid returned to the processing liquid source side is suctioned into the pump together with the processing liquid replenished from the processing liquid source. The processing liquid passes through the filter device in at least one of the returning step and the replenishing step. The amount of the processing liquid returned to the processing liquid source side in the returning step is larger than the amount of the processing liquid ejected from the ejecting part in the ejecting step.

  • Patent number: 8851011
    Abstract: In a coating step, a substrate is rotated at a high speed, and in that state a resist solution is discharged from a first nozzle to a central portion of the substrate to apply the resist solution over the substrate. Subsequently, in a flattening step, the rotation of the substrate is decelerated and the substrate is rotated at a low speed to flatten the resist solution on the substrate. In this event, the discharge of the resist solution by the first nozzle in the coating step is performed until a middle of the flattening step, and when the discharge of the resist solution is finished in the flattening step, the first nozzle is moved to move a discharge position of the resist solution from the central portion of the substrate. According to the present invention, the resist solution can be applied uniformly within the substrate.

  • Publication number: 20140174475
    Abstract: A filtration efficiency, which is similar to the filtration efficiency obtained when a plurality of filters are provided, can be obtained by one filter, and decrease in throughput can be prevented. Based on a control signal from a control unit 101, a resist liquid L is sucked into a pump 70 through a filter. A part of the resist liquid sucked in the pump is discharged from a discharge nozzle 7. The remaining resist liquid is returned to a supply conduit 51b on a primary side of the filter. A process is synthesized by adding a replenishment amount equal to the discharge amount to the return amount. The discharge of the synthesized process liquid and the filtration thereof by the filter are performed the number of times corresponding to a rate between the discharge amount and the return amount.
