  • Patent number: 8755034
    Abstract: According to an example embodiment, a method to determine an exposure start position and orientation includes loading a substrate on a moving table. The substrate includes at least one alignment mark of a first set of alignment marks of a first pattern layer patterned thereon. At least one alignment mark of a second set of alignment marks of a second pattern layer is exposed on the substrate using maskless lithography. A position of the at least one alignment mark of the first set of alignment marks and a position of the at least one alignment mark of the second set of alignment marks on the substrate is measured. A relative orientation difference between a desired exposure start orientation and an obtained exposure start orientation is acquired using the measured positions of the at least one alignment mark of the first set of alignment marks and the at least one alignment mark of the second set of alignment marks.
