Abstract:
An imprint apparatus includes a substrate holder including a plurality of chucking regions for chucking a substrate, and a controller that controls chucking forces of the chucking regions. The chucking regions include a first chucking region for chucking a periphery of a first substrate having a first diameter, a second chucking region for chucking a periphery of a second substrate having a second diameter larger than the first diameter, a third chucking region group divided into a plurality of regions inside the first chucking region, and a fourth chucking region group divided into a plurality of regions between the first chucking region and the second chucking region. The controller controls the chucking forces of each of the chucking regions.
