Patent ID: 10856422

Abstract:
Method of forming a pattern by arranging a photocurable composition on a substrate; bringing a mold having a concavo-convex pattern into contact with the composition; irradiating the composition with light to form a cured film; releasing the mold from the cured film; forming a reversal layer on the cured film having a concavo-convex pattern transferred from the mold; partially removing the reversal layer to expose the convexes of the pattern in such a manner that the reversal layer remains in the concaves of the pattern formed on the cured film; and etching the photocurable composition layer using the reversal layer remaining in the concaves as a mask to form a reversal pattern, wherein the mold is brought into contact with the photocurable composition in an atmosphere of a soluble gas having a solubility in the composition; and the soluble gas has a saturation solubility of 38% by volume or more.
