Patent ID: 8142694

Claim:
A method for forming an imprint pattern, comprising: contacting a template having a first pattern with a curable material on a substrate to be treated and curing the curable material; releasing the template from the curable material after curing to form a second pattern made of the curable material such that the first pattern is transferred and formed as the second pattern for the substrate; measuring at least one of a load or time requiring for separation of the template when the template is separated from the curable material after transferring and forming; and comparing the load or time measured with a predetermined threshold value and determining whether the load or time measured is beyond the predetermined threshold value or not; wherein the predetermined threshold value is determined computationally on a pattern surface area of the template; wherein the predetermined threshold value is calculated by obtaining the pattern surface area of the template, dividing a pattern forming surface of the template into small regions, obtaining the load or time requiring for the separation of the template per each of the small regions, obtaining deformation volume of the template during and after the separation of the template so that a dimension of the second pattern after the template is separated is obtained, and comparing the pattern surface area of the second pattern with a designed dimension and an allowable margin thereof so as to obtain, as the predetermined threshold value, separation loads or separation times at an upper limit value and lower limit value of the pattern surface area of the second pattern based on the designed dimension and the allowable margin.
