Abstract

A lithography apparatus includes an original holder configured to hold and move an original, a measurement unit configured to measure a misalignment amount of the original with respect to the original holder, and a controller configured to control movement of the original holder. The controller repeatedly performs preliminary driving for moving the original holder before performing the pattern formation. At this time, if the misalignment amount measured by the measurement unit converges to a predetermined convergence value while the preliminary driving is repeatedly performed, the controller ends the preliminary driving.
