An imprint apparatus according to an exemplary embodiment of the present disclosure, the imprinting apparatus forming a pattern on a region of a substrate to be processed using a mold, the imprint apparatus including a mount portion on which the substrate is mounted, and a heating unit that heats the region to be processed. On the basis of information related to a difference in shape between a pattern area of the mold and the region to be processed and information related to a contact pressure exerted between the substrate and the mount portion, the heating unit heats the region to be processed such that the difference in shape between the pattern area of the mold and the region to be processed is reduced.

A method of manufacturing a window includes a thermoforming step of pressurizing and thermoforming a first window disposed between a pressing frame and a receiving frame to form a second window, by moving the pressing frame in a first direction facing the receiving frame, wherein the first window includes a first flat portion, first curved portions bent at a curvature from the first flat portion, and a first corner portion between two adjacent first curved portions among the first curved portions, and the second window includes a second flat portion, second curved portions bent at a curvature from the second flat portion, and a second corner portion between two adjacent second curved portions among the second curved portions.
