    摘要: 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.
