Abstract:
1. A nano-imprint lithography method, comprising: imprinting polymerizable material positioned on a substrate by contacting the polymerizable material with a template to form a patterned layer on the substrate, the template coupled to a chuck and constrained against first and second template supports of the chuck, the first and second template supports defining an imprint outer bend zone, the first template support provided at a first distance from an edge of the patterned layer, the first distance defining a first free span length along the template; prior to separating the template from the patterned layer and while the template remains in contact with the patterned layer, adjusting the chuck to constrain the template against the second template support and a third template support of the chuck and releasing the constraint against the first support, the second and third supports defining a separation outer bend zone that cinctures the imprint outer bend zone, with the second template support provided at a second distance from an edge of the patterned layer, the second distance defining a second free span length along the template and wherein the first free span length is less than the second free span length; and separating the template and the patterned layer.
