摘要： According to one embodiment, an imprint method comprises coating a photo-curable organic material on a film to be processed, bringing a concave-convex pattern of a template into contact with the photo-curable organic material, applying a force to the template in such a state that the template is brought into contact with the photo-curable organic material, curing the photo-curable organic material by irradiating light onto the photo-curable organic material, in such a state that the template is brought into contact with the photo-curable organic material, and releasing the template from the photo-curable organic material after the light irradiation. The force applied to the template corresponds to a gap between a surface of the film to be processed and the template.

摘要： An exposure method includes setting a photo mask into an exposure apparatus. The exposure apparatus includes an opening/closing unit configured to block a part of exposure light from a light source to the wafer. The photo mask having a product area in which a pattern to be used when a central part of a wafer is exposed is formed and peripheral exposure areas in each of which a pattern to be used when a peripheral area is exposed is formed. The peripheral exposure areas are formed to have a plurality of types of pattern densities. Then, a peripheral part of the wafer exposed. When exposing, the opening/closing unit is opened such that one or more of exposed photo mask areas selected from among the peripheral exposure areas has a pattern density corresponding to a shot position of the peripheral part.
