  • Patent number: 9358588
    Abstract: The present invention provides a substrate cleaning method capable of removing particles from the entire surface of a substrate to be processed at a high removing efficiency. In the substrate cleaning method according to the present invention, a substrate to be processed W is immersed in a cleaning liquid in a cleaning tank 12. Then, ultrasonic waves are generated in the cleaning liquid contained in the cleaning tank 12, so that the substrate to be processed W is subjected to an ultrasonic cleaning process. While the substrate to be processed is being cleaned, a dissolved gas concentration of a gas dissolved in the cleaning liquid contained in the cleaning tank is changed.

  • Patent number: 9046866
    Abstract: A cleaning device includes first and second cleaning members and a moving member. The first cleaning member contacts a surface of a rotating member, which is in contact with an image carrier, to clean the rotating member by removing substances attached thereto. The moving member supports the first cleaning member in a movable manner. The second cleaning member is disposed downstream of the first cleaning member in a rotation direction in which the rotating member rotates and contacts the surface of the rotating member to clean the rotating member by removing the substances. The second cleaning member removes the substances that remain on the surface of the rotating member after the first cleaning member has been separated from the rotating member so that the substances are removed before a part of the surface of the rotating member on which the substances remain comes into contact with the image carrier.

  • Patent number: 9004079
    Abstract: Disclosed is a substrate processing apparatus capable of drying a substrate to be processed while suppressing the pattern collapse or the occurrence of contamination. A substrate is held in a liquid bath while being immersed in a liquid, and the liquid bath is disposed in a processing space of a processing vessel. A processing of drying the substrate is performed by replacing the liquid in the liquid bath with a supercritical-state fluid. A predetermined mechanism moves liquid bath between a processing location in the processing case and a stand-by location outside the processing case. A heater installed in the processing case changes the fluid to a supercritical state or maintains the supercritical state while cooling mechanisms cool down the liquid bath moved to the stand-by location outside the processing vessel.

  • Patent number: 8944078
    Abstract: Disclosed is a substrate processing apparatus capable of drying a substrate to be processed while suppressing a pattern collapse or occurrence of contamination. In a processing vessel, a substrate is immersed in a liquid in the longitudinal direction, and the liquid is pushed out by a substitution fluid of a supercritical state to be discharged from the processing vessel. Thereafter, the substitution fluid subjected to the substitution with the liquid is discharged from the processing vessel to depressurize the processing vessel, and the substitution fluid is changed from the supercritical state to a gaseous state to dry the substrate.

The process-liquid supplying mechanism 30 includes a first chemical-liquid supply mechanism that supplies a hydrofluoric process liquid, and a drying-liquid supplying mechanism that supplies an organic solvent for drying a wafer W. A control part 50 causes the first chemical-liquid supplying mechanism to supply a hydrofluoric process liquid, and then causes the drying-liquid supplying mechanism to supply an organic solvent. In addition, before the control part 50 causes the drying-liquid supplying mechanism to supply an organic solvent, the control part causes a cleaning mechanism 10 to remove an alkaline component in a casing 5.
