摘要:
A system for manufacturing a semiconductor device which predicts a difference in registration error between a circuit pattern and an overlay mark from a pattern dimension, illumination conditions and the wave aberration of an exposure lens, feeds a correction value based on the predicted difference back to an exposure device and modifies an overlay inspection data control limit.
