Abstract
A new exposure method, which provides both high X-ray intensity and do se uniformity in a large exposure field for SR lithography, is discuss ed. This method uses a scanning mirror method and electron beam wobbli ng in combination in SR beamlines. Simulation results show that dose u niformity of less than or equal to +/-2% will be achieved in the 50-mm -square exposure field by this method. The advantage of this method wa s confirmed by experiments in the 25-mm-square field.
