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 apparatus. SOLUTION: A cleaning apparatus for immersion lithographic apparatus comprises a substrate table so configured as to hold a substrate, a projection system PS configured to project a patterned radiation beam onto the substrate, a megasonic transducer 20 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 lithographic projection apparatus is cleaned using megasonic waves generated from the megasonic transducer configured to clean the surface. COPYRIGHT: (C)2011,JPO&INPIT
