发明名称 Exposure method, method of production of density filter, and exposure apparatus
摘要 <p>A method of exposure while gradually reducing the exposure at peripheral parts when transferring patterns to a plurality of areas on a substrate where the peripheral parts are partially superposed, including exposing one shot area of the substrate through a density filter set so that the energy at the peripheral parts becomes a predetermined first distribution, measuring the distribution of exposure at portions corresponding to the peripheral parts on the substrate, determining a second distribution where the exposure at the peripheral parts becomes a target value based on the measured distribution of exposure, and exposes the shot areas adjoining the one shot area through a density filter set to give the second distribution.</p>
