Abstract
An aligner evaluation system includes (a) an error calculation module configured to calculate error information on mutual optical system errors among a plurality of aligners; (b) a simulation module configured to simulate device patterns to be delineated by each of the aligners based on the error information; and (c) a evaluation module configured to evaluate whether each of the aligners has appropriate performances for implementing an organization of a product development machine group based on the simulated device pattern.
