Abstract:
An exposure apparatus comprising:means for providing electronic data representing a circuit pattern; division processing means for dividing the circuit pattern in the form of the electronic data into a plurality of regions so that adjacent ones of the regions may partly overlap each other; exposure means, comprising: (i) a plurality of image display means for displaying the circuit pattern in correspondence with respective portions of the electronic data corresponding to each divided region of the plurality of regions, and (ii) a plurality of optical systems that project respective ones of the divided regions displayed by the plurality of image display means onto a resist surface of a substrate; and control means for, while causing duplex regions of the adjacent regions to overlap with each other on the resist surface of the substrate, causing the plurality of divided regions to be simultaneously projected onto the resist surface by the exposure means to thereby cause an image of one unit of circuit pattern to be formed on the resist surface of the substrate.
