1. An imprint apparatus that executes imprint processing including,
a contact process of bringing imprint material on a substrate and a mold in contact with each other,
an alignment process of performing alignment of the substrate and the mold after the contact process, and
a curing process of curing the imprint material after the alignment process,
the imprint apparatus comprising:
a first light source configured to generate first light that deforms the substrate for alignment of the substrate and the mold;
a second light source configured to generate second light that partially cures the imprint material; and
a modulator configured to generate first modulated light obtained by modulating the first light, and second modulated light obtained by modulating the second light,
wherein either of the first modulated light and the second modulated light is selectively provided onto the substrate, and in the alignment process, switching between the first modulated light being provided onto the substrate and the second modulated light being provided onto the substrate is executed at least two times.
