摘要:
The present invention features a method to determine relative spatial parameters between two coordinate systems, which may be a mold and a region of a substrate in which mold is employed to generate a pattern. The method includes sensing relative alignment between the two coordinate systems at multiple points and determines relative spatial parameters therebetween. The relative spatial parameters include a relative area and a relative shape.

An imprint lithography system operable for imprinting a pattern into a material deposited between an imprint mold and a substrate, the system including, inter alia, a first set of imaging units positioned at a first angle relative to normal of the substrate; and a second set of imaging units positioned at a second angle relative to normal of the substrate, wherein the first and second angles are not equal to each other.

摘要:
Systems and methods for improving robust layer separation during the separation process of an imprint lithography process are described. Included are methods of matching strains between a substrate to be imprinted and the template, varying or modifying the forces applied to the template and/or the substrate during separation, or varying or modifying the kinetics of the separation process.
