Exposure method, exposure apparatus, method for adjusting the exposure apparatus, and device manufacturing method

摘要

Attention is paid to the phenomenon that a static image distortion characteristic is averaged in the width of a projection area in a scanning direction and becomes a dynamic image distortion characteristic, when a mask pattern is scan-exposed onto a photosensitized substrate by a projection exposure apparatus. At least a random component included in the dynamic image distortion characteristic is corrected by arranging an image correction plate obtained by locally polishing the surface of a transparent parallel plate. Correction plates which minimize other aberrations beforehand are manufactured and installed within a projection optical path, considering that also the other aberrations are averaged and become dynamic aberration characteristics at the time of scan-exposure.
