Abstract
A method can include placing a substrate over a chucking region, wherein the substrate has a primary surface; quantifying a distortion in the substrate, the lithographic template, the imprint apparatus, or any combination thereof; and dispensing a formable material based at least in part on the distortion. The distortion can include a deviation in planarity, a magnification or orthogonality error or the like. In another aspect, an imprint apparatus can include a substrate holder including a chucking region; a template having an imprint surface that includes protrusions, wherein the protrusions define a primary surface; and a processor configured to determine an amount of a formable material to dispense in a particular area based at least in part on an distortion in the substrate, the lithographic template, the imprint apparatus, or any combination thereof.
