Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a lithography projection apparatus and a device manufacturing method, capable of compensating for or improving the effect of a thick pellicle. SOLUTION: The thick pellicle is used to calculate corrections to be applied in exposure so that the thick pellicle is allowed to have a non-flat shape, and the shape compensates for the optical effect of the pellicle. In order for the pellicle to more readily compensate for, to be mounted, in such a manner as to employ a one-dimensional shape under the influence of gravity. COPYRIGHT: (C)2008,JPO&INPIT |
