Abstract: The disclosed nanoimprinting method suppresses fluctuations in thickness of residual film and defects due to residual gas in a resist film, onto which a pattern of protrusions and recesses is transferred, in a nanoimprinting method that employs the ink jet method to coat a substrate with droplets of resist material. Droplets are coated onto a substrate such that the spaces between the droplets along an A direction which is substantially parallel to the direction of the lines of a linear pattern of protrusions and recesses are longer than the spaces between the droplets in a B direction which is substantially perpendicular to the A direction, in a nanoimprinting method that coats a substrate with the droplets of a resist material using the ink jet method.

Abstract: Positions on a mold at which foreign matter is present are detected, and adhered position information related to the positions is obtained. Corresponding position information related to positions on a substrate, which are positions that correspond to the positions of the foreign matter when a pattern of protrusions and recesses and a surface of the substrate on which a curable composition is coated face each other and undergo a predetermined positioning operation, is generated based on the adhered position information. At least one droplet of the curable composition is arranged at the positions of the substrate. The pattern of protrusions and recesses is pressed against the surface of the substrate on which the composition is coated while administering the predetermined positioning operation. The curable composition is cured, and the mold is separated from the cured composition. Thereby, foreign matter adhered to molds can be removed efficiently and at low cost.

Abstract: A nanoimprinting mold has a fine pattern of protrusions and recesses constituted by a plurality of linear protrusions and a plurality of recesses on the surface thereof. The pattern of protrusions and recesses includes at least one recess having an end portion of a predetermined shape. The predetermined shape is that which has a cross section with a smaller aspect ratio than an aspect ratio of a cross section of a connecting portion, which is a portion of the recess having the end portion other than the end portion and continuous therewith. Thereby, the collapse of the end portions of protrusions of a pattern on curable resin when a mold is pressed against the curable resin on a substrate then separated therefrom can be suppressed, in nanoimprinting that employs a mold having a predetermined fine pattern of protrusions and recesses on the surface thereof.
