A digital exposure device includes: a stage having a substrate seated thereon where a pattern is to be formed and moving in a scan direction; a data modification unit receiving design data and generating modified data by extending the design data; and a digital exposure unit receiving the design data and projecting a light controlled according to the design data on the substrate, wherein the modified data includes intermedial data corresponding to the size difference between an image of the design data and an image of the modified data and some of unit data forming the intermedial data are data obtained when unit data of the design data are shifted in any expansion direction.

Digital exposure device

Provided is a digital exposure device. The digital exposure device includes a stage mounted with a substrate on which a pattern is formed, a first light source, a first head, and a digital micro-mirror device control unit. The stage is configured to move in a scan direction. The first light source is configured to provide a first light. The first head is spaced apart from the stage in a first direction and is configured to receive the first light, to generate at least one spot beam by modulating the first light, and to project the at least one spot beam onto the substrate. The digital micro-mirror device control unit is configured to control an energy of the at least one spot beam generated from the first head to be inversely proportional to a size of the at least spot beam generated from the first head.
