Claim 0:
1. An imprint apparatus that performs, on a plurality of shot regions of a substrate, an imprint process for transferring a pattern of a mold to an imprint material arranged on the substrate, the apparatus comprising:
a detector configured to detect a first mark provided in the substrate and a second mark provided in the mold; and
a controller programmed to perform alignment between a shot region selected from the plurality of shot regions and the mold based on an output of the detector by:
determining a second driving amount for driving the detector to perform the alignment between the selected shot region and the mold in accordance with a first driving amount, held in a storage, by which the detector is to be driven to fit the first mark and the second mark within a specific region of a field of view of the detector, and a correction value, obtained during alignment of a previous shot region and held in the storage, used to correct the first driving amount, wherein the correction value indicates a shift amount, at the time of the alignment, between a center position of the field of view of the detector and a representative position decided by the first mark and the second mark;
controlling positioning of the detector based on the determined second driving amount to perform the alignment between the selected shot region and the mold; and
updating the correction value held in the storage, and to be used during alignment of a subsequent shot region, based on the output of the detector at a time of performing the alignment for the selected shot region.
