A lithography device includes: a pattern forming unit that forms a pattern in a shot region on a substrate held by a substrate holding unit by using a pattern unit; an acquisition unit that acquires relationships among the amount of positional deviation of the substrate relative to the substrate holding unit, a holding force applied to at least a part of the substrate to hold the substrate, and an overlapping error between the substrate and the pattern unit; a measurement unit that measures the amount of positional deviation of the substrate relative to the substrate holding unit; and a control unit that controls the holding force to reduce the overlapping error between the substrate and the pattern unit on the basis of the amount of positional deviation measured by the measuring unit and the relationships acquired by the acquisition unit.
