Abstract:
Systems and methods of aligning a lithographic mask are described. In one aspect, a substrate and a lithographic mask are aligned based at least in part on a motive force between a substrate alignment mark on the substrate and a mask alignment mark on the lithographic mask that induces movement of at least one of the substrate and the lithographic mask into mutual alignment.
