Projection exposing apparatus and projection exposing method
摘要:
A projection exposing apparatus has a second photo-mask disposed on a blind for determining a region to be exposed to deformed light beams, the circuit pattern of the second photo-mask being the same as or arranged to correspond to the circuit pattern of a first photo-mask to be projected onto a substrate The deformed irradiation light beams are applied to the second photo-mask circuit pattern to image diffracted light beams on the substrate and project the circuit pattern.
