Patent ID: 7214624

Claim:
A method of forming a resist pattern comprising the steps of: preparing a substrate on which a resist layer is formed and a mold having a concavo-convex surface including protrusion and recess forming a pattern; transferring the pattern of the mold to the resist layer on the substrate by an imprinting method; and etching a side surface of a protrusion of a resist pattern transferred to the resist layer so as to form the protrusion having a width narrower than a width of the corresponding recess formed to the mold wherein the etching to the side surface of the protrusion of the resist pattern is carried out together with removal of a layer of the resist remaining in the recess of the transferred resist pattern, and at least one of a thickness of the resist remaining layer and a width of the recess of the mold is changed so that the protrusion of the resist pattern provides a predetermined width at substantially the same time as completion of the removal of the resist remaining layer.
