Patent number: 9004079Abstract: 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.Type: GrantFiled: April 1, 2011Date of Patent: April 14, 2015Assignee: Tokyo Electron LimitedInventor: Yuji Kamikawa

Patent number: 6401353Abstract: A substrate dryer causing no water mark on a substrate having a refined·complicated structure and capable of suppressing increase of a cost required for a drying treatment is provided. Drying gas of low-molecular silicone generated in a drying gas generation part is heated by a heater and thereafter supplied from a drying gas supply nozzle. The drying gas is supplied to the main surface of a substrate being pulled up from de-ionized water stored in a cleaning bath as a stream. Silicone contained in the drying gas is condensed on the surface of the substrate, substitutes for moisture, and thereafter vaporizes. Silicone is excellent in permeability·dryability, and hence can suppress formation of a water mark also on a substrate having a refined·complicated structure. Further, silicone applies no load to the environment, and hence increase of a cost required for the drying treatment can be suppressed without requiring specific treatment for disposal.Type: GrantFiled: March 7, 2001Date of Patent: June 11, 2002Assignee: Dainippon Screen Mfg.
