Abstract
A method for forming a pattern by using a photo-nanoimprint process includes performing, on each of a plurality of shot areas on a surface of a substrate: a step (1) of dispensing liquid droplets of a curable composition (A) dropwise discretely; a step (2) of bringing the curable composition (A) and a mold into contact with each other; a step (3) of irradiating the curable composition (A) with light; and a step (4) of releasing the mold from a cured product of the curable composition (A), in which when steps from the step (2) to the step (4) are collectively called an imprinting step (Im), before the imprinting step (Im) is performed on one shot area on which the step (1) has already been performed out of the plurality of shot areas, the step (1) is performed on another shot area selected from the plurality of shot areas.
