Patent ID: 8444889

Claim:
An imprint pattern forming method comprising: contacting a template with a pattern in a front surface with an imprint material formed in a substrate to fill the imprint material into the pattern, wherein the template protrudes toward the front surface when applying pressure to a back surface of the template; curing the imprint material filled in the pattern to form an imprint material pattern; after forming the imprint material pattern, separating the template from the imprint material pattern while applying pressure to the back surface of the template, wherein while the template is being separated from the imprint material pattern, the substrate does not protrude and only the template protrudes; and determining a timing for applying the pressure to the back surface of the template, by performing a simulation of a separation between the template and the imprint material, with a design data of the template, wherein the applying the pressure to the back surface of the template is based on the timing, and wherein while the template is being separated from the imprint material pattern, the pressure applied to the back surface of the template is changed.
