Claim 11:
12. An apparatus that forms a cured product of an curable material on a substrate by using a member, the apparatus comprising:
a holder that holds the member;
an optical system that irradiates the curable material on the substrate with irradiation light for increasing a viscosity of the curable material; and
a control unit composed of a computer configured to execute a program that:
causes the optical system to provide the irradiation light such that the irradiation light has a light intensity distribution in which a light intensity increases from a center of contact region where the member and the substrate are in contact toward a side surface of the contact region, and
while the member and the curable material on the substrate are in contact with each other, causes the optical system to irradiate, with the irradiation light having the light intensity smaller than a peak of the light intensity distribution, a boundary surface of the curable material between the member and the substrate that moves from the center of the contact region toward the side surface of the contact region in a region including the side surface of the contact region.
