Claim 11:
12. An article manufacturing method comprising:
forming a pattern on a substrate using an imprint apparatus including:
a control unit configured to determine a first exposure amount of a first light irradiation and a second exposure amount of a second light irradiation such that a viscosity resistance of the imprint material in a pattern region of the substrate after the first light irradiation and the second light irradiation does not exceed a first threshold;
a first irradiation unit configured to perform the first light irradiation of the imprint material on the substrate to incompletely cure the imprint material in the pattern region before bringing the mold into contact with the imprint material on the substrate for the aligning;
a second irradiation unit configured to perform the second light irradiation of the imprint material on the substrate to further incompletely cure the imprint material in the pattern region, in the aligning; and
a third irradiation unit configured to perform third light irradiation of the imprint material on the substrate to completely cure the imprint material in the pattern region, in the curing; and

processing the substrate with the pattern formed thereon,
wherein an article is manufactured from the processed substrate.
