Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic projection apparatus, which minimizes an effect of gas vibrations or gas pressure changes around an exposure system, which are caused by the actuation of a movable part of the exposure system or of another system in a housing, on the position of a board. SOLUTION: The lithographic projection apparatus includes a position disturbance correcting system, which offsets a disturbance of the position of a board holder 19 holding the board 13. In the apparatus, a space 3 including the exposure system is separated by a holed wall 5 and is separated from a space 4 including another system by a movable wall 10. The space 3, therefore, damps or cuts off the vibrations or pressure changes of the gas. The vibrations of the gas may be offset by a speaker 61. This lithograph apparatus can be employed to provide a novel device manufacturing method. COPYRIGHT: (C)2005,JPO&NCIPI
