Abstract:
A scanning exposure method comprising:moving each of a mask and a substrate independently to move the mask and the substrate synchronously;emitting a plurality of light pulses during the synchronous movement of the mask and the substrate;irradiating, during said synchronous movement, each of a plurality of regions on the substrate with at least one of the plurality of light pulses, wherein the plurality of regions are within an irradiation area of the light pulses, and integrated light quantities provided on said plurality of regions vary among said plurality of regions and wherein integrated numbers of pulses provided on the plurality of regions vary among the plurality of regions; andadjusting, during synchronous movement, intensity of a next light pulse to be irradiated on the substrate, based on a light quantity of at least one of said plurality of light pulses.
