Abstract
An example embodiment relates to an alignment device including an optical aligner system including a plurality of aligners configured to measure a position of a workpiece having a plurality of alignment marks, and an optical member. The optical member is configured to diverge alignment beams reflected from neighboring alignment marks of the plurality of alignment marks and transmit the beams to neighboring aligners of the plurality of aligners respectively if a distance between the neighboring aligners is greater than a distance between the neighboring alignment marks.
