Patent ID: 8158048

Claim:
A method for forming a resin pattern using a mold by nanoimprint lithography, comprising: applying a resin to a substrate to prepare a transferred object; placing a mold directly on the transferred object or placing the transferred object directly on a mold, the mold comprising a main mold including a fine pattern of a protrusion and a depression intended to be transferred onto the transferred object; and a spacer for forming a space between the protrusion of the fine pattern of the main mold and the transferred object, the spacer having a vent passage capable of flowing gas therethrough; heating the transferred object to a temperature above a glass transition temperature of the resin; exhausting gas generated as the resin temperature is elevated through the vent passage of the spacer by evacuating the inside of the mold to a low vacuum not less than 1 hPa; and pressing the mold and elastically deforming the spacer to transfer the fine pattern of the main mold into the softened resin, the spacer further having a Young's modulus in a compression direction within a range from 50 to 500 MPa at the temperature of the mold during the pattern transfer with the vent passage of the spacer being not completely blocked by a pressing force during the pattern transfer to achieve uniform as flow.
