Method for producing substrate with fine projection-and-recess pattern, and substrate with fine projection-and-recess pattern obtained thereby

摘要

A method for producing a substrate with a fine projection-and-recess pattern which is excellent in productivity and achieves excellent pattern feature size and accuracy is provided. The method for producing a substrate with a fine projection-and-recess pattern 50 by photo-nanoimprint lithography includes: a first step S1 of applying a photocurable composition 2 to a substrate 1 to form a composition-applied substrate 10; a second step S2 of pressing a mold 20 provided with a fine projection-and-recess pattern into contact with the composition-applied substrate 10 to mold the photocurable composition 2 into recesses 5a and projections 5b; a third step S3 of irradiating the photocurable composition 2 with an active energy line to cure the photocurable composition 2 of the recesses 5a and the projections 5b and peeling off the mold 20; a fourth step S4 of removing the cured recesses 5a and etching the substrate 1 located on the lower surface of the recesses 5a; and a fifth step S5 of removing the cured projections 5b. At the first step S1, the photocurable composition 2 is applied to the substrate 1 by printing using a printing plate.
