Abstract:
PURPOSE: A cleaning device, a lithography device, and a method for cleaning the lithography device are provided to efficiently clean an immersion lithographic projection apparatus using a megasonic wave through liquid. CONSTITUTION: A megasonic transducer(20) cleans the surface of an immersion lithographic projection apparatus. A liquid supply system supplies liquid between the megasonic transducer and the surface to be cleaned. A cleaning solution outlet provides a space for discharging a liquid solution(30) formed on the surface of the megasonic transducer.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of effectively cleaning an immersion lithographic equipment. SOLUTION: The immersion lithographic equipment comprises a substrate so configured as to hold a substrate, a projection system configured to project a patterned radiation beam onto the substrate, a megasonic transducer configured to clean a surface, and a liquid supply system configured to supply a liquid between the megasonic transducer and the surface to be cleaned. The surface of the immersion lithography projector is cleaned using megasonic waves generated from the megasonic transducer configured to clean the surface. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus which is easily and effectively cleaned, and to provide a cleaning method to effectively clean the liquid immersion lithographic apparatus. SOLUTION: A cleaning tool to clean a surface of a component of the lithographic apparatus is disclosed. The cleaning tool includes a sonic transducer, a liquid supply mechanism to supply liquid to a reservoir between the surface to be cleaned and the sonic transducer, and a liquid outlet to discharge the liquid supplied by the liquid supply mechanism. The cleaning tool is constituted so that the liquid may flow into the liquid outlet under operation of gravity when used. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus which carries out cleaning readily and effectively, and also to provide a method for effectively cleaning an immersion lithographic apparatus. SOLUTION: A cleaning tool to clean a surface of a liquid confinement system of an immersion lithographic apparatus is disclosed, and the liquid confinement system has an aperture to allow passage of a beam of radiation through the liquid confinement system of an immersion lithographic apparatus. The cleaning tool includes: a sonic transducer; a reservoir configured to hold liquid between the sonic transducer and the surface to be cleaned; and a barrier positioned in the reservoir under the aperture to form, in use, a shield to sonic waves.
