Classification: CPC G  B | IPC B  G

Claim 0:
1. An imprint apparatus that performs an imprint process of forming a pattern of an imprint material on a substrate using a mold, comprising:
a mold holding unit configured to hold the mold, the mold including a plurality of marks;
a stage configured to hold the substrate, wherein a plurality of reference marks are provided on the stage;
a measurement unit including at least one scope configured to measure the plurality of marks of the mold held by the mold holding unit;
a driving unit configured to adjust a distance between the mold held by the mold holding unit and the substrate held by the stage;
a curing unit configured to cure the imprint material;
a memory configured to store instructions; and
a processor communicatively connected to the memory and configured to execute the stored instructions to function as a control unit configured to:
control the imprint apparatus to perform the imprint process including a process of driving the driving unit so that the mold held by the mold holding unit is brought into contact with the imprint material on the substrate held by the stage, a process of curing the imprint material using the curing unit while the mold and the imprint material are in contact with each other, and a process of driving the driving unit so that the mold is separated from the cured imprint material;
obtain information about a difference between a first position shift amount obtained by simultaneously measuring the plurality of marks of the mold and the plurality of reference marks on the stage by the measurement unit before bringing the mold into contact with the imprint material on the substrate in a first imprint process and a second position shift amount obtained by simultaneously measuring the plurality of marks of the mold and the plurality of reference marks on the stage by the measurement unit after separating the mold from the imprint material in the first imprint process; and
control the imprint apparatus to perform a second imprint process, following the first imprint process in which the first position shift amount and the second position shift amount are obtained, based at least on the obtained information about the difference between the first position shift amount and the second position shift amount.
