Abstract

An X-ray lithography system, in which an X-ray beam is separated from synchrotron radiation beams and reflected by a scanning mirror which vertically scans the reflected X-ray beam. The X-ray is irradiated into an exposure chamber via a beryllium window, which is vertically oscillated in such a manner that the beryllium window is shifted up and down in synchronization with the scanning operation of the X-ray beam.
