Claim 15:
16. 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 configured to:
control, based on a driving amount, held in a storage, by which the detector was driven with respect to the first and second marks to fit the first and second marks within a specific region of a field of view of the detector when alignment between the mold and a first shot region selected from the plurality of shot regions was performed based on an output of the detector, positioning of the detector for alignment between the mold and a second shot region, which is different from the first shot region and selected from the plurality of shot regions, wherein the positioning of the detector includes 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; and
update the driving amount, held in the storage, based on the output of the detector when alignment between the mold and the second shot region was performed, the updated driving amount to be used at a time of performing alignment for a third shot region, which is different from the first shot region and the second shot region and which is selected from the plurality of shot regions.
