ABSTRACT:
A scanning exposure apparatus includes a masking blade provided between an optical integrator and an optical system, and which is movable in a predetermined direction on a plane perpendicular to an optical axis of the optical system. The masking blade has a pair of edges substantially parallel to each other and perpendicular to the predetermined direction in the plane, and is moved so that the pair of edges are respectively imaged at a beginning and an end of scanning exposure onto a light shielding border by the optical system to change a width of an illuminated region with respect to a scan direction at both the beginning and the end of the scanning exposure.
