At the time of transferring the pattern image of a mask onto a substrate, an exposure apparatus overlays peripheral portions of exposure areas with respect to a pattern image, which has previously been transferred onto the substrate, with each other, and transfers a predetermined pattern onto the substrate. This exposure apparatus comprises a dose adjusting device capable of adjusting the dose of exposure light at the overlying portion, a shape measuring unit for measuring the shape of the pattern image of the overlying portion formed on the substrate, and a control section for controlling the dose adjusting device based on the result of measurement by the shape measuring unit in such a way that the shape of the pattern image of the overlying portion formed on the substrate becomes an intended shape.
