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.

Methods for locating an alignment mark on a substrate are described. Generally, the substrate includes one or more locator marks adjacent to a substrate alignment mark. Locator marks provide the relative location of the substrate alignment mark such that the substrate alignment mark may be used in aligning a substrate with a template within a lithographic system with a reduced magnitude of relative displacement.
