  • Patent number: 11698583
    Abstract: An imprint apparatus is operable to perform an imprint process, which is for forming a pattern on an imprint material on a substrate by using a mold, for each of shot regions of the substrate. The apparatus includes a controller configured to control alignment between the mold and the substrate. The controller determines a target position obtained by adding a predetermined additional amount to a movement amount of a substrate stage according to a positional deviation between the mold and the substrate, starts movement of the stage towards the determined target position, and starts curing of the imprint material by a curing device at a timing at which the detected positional deviation falls within an allowable range during the movement of the stage.
