摘要

A method of exposing a wafer to a light comprises transferring an image onto a plurality of shot areas by irradiating a projection light, each of the plurality of shot areas including at least one die area defined on the wafer on which a photoresist film is formed, and scanning the at least one die area adjacent to an edge portion of the wafer by irradiating a scanning light.
