Abstract
In a method of aligning a substrate, a first alignment mark in a single shot region on the substrate may be identified. A second alignment mark in the single shot region may be selectively identified in accordance with the identification of the first alignment mark. The substrate may then be aligned using identified any one of the first alignment mark and the second alignment mark. Thus, although the substrate may be accurately aligned, the accurately aligned substrate may not be determined to be misaligned.
