Title: Exposure apparatus, method for manufacturing flat panel display, and method for manufacturing device
Inventor: AOKI YASUO
IPC: G03F7/20
Filed: 2010-09-07
Abstract: PROBLEM TO BE SOLVED: To achieve weight saving and downsizing of a mask stage apparatus for a large exposure apparatus.SOLUTION: In a mask stage MST, when a stage body 60 holding a mask M moves in a Y-axis (cross-scan) direction, it moves integrally with a pair of X beams 70 and a pair of X tables 90 in the Y-axis direction. In contrast, when the stage body 60 moves in an X-axis (scan) direction, the pair of X tables 90 moves with the stage body 60 over the stationary X beams 70 in the X-axis direction. Therefore, low thrust of a linear motor may be enough to move the mask M in the scan direction, and influence of driving reaction force can be reduced. In addition, when the mask stage MST moves in the Y-axis direction, a pair of stage guides 50 simultaneously moves in the Y-axis direction, and consequently a width of the stage guides 50 in the Y-axis direction can be reduced, thus weight saving of a mask stage apparatus can be achieved.
