ABSTRACT:
An exposure apparatus for transferring a pattern, formed on a membrane of a mask, to an exposure region of a wafer disposed opposed to the mask with a small spacing kept therebetween. The apparatus includes an exposure system for transferring, by exposure, the pattern of the mask to different exposure regions of the wafer sequentially, a measuring system for producing deformation information related to at least one portion of the mask membrane, and an attitude controlling system for controlling attitude of at least one of the mask and the wafer, on the basis of the deformation information produced by the measuring system.
