EXPOSURE APPARATUS AND METHOD FOR MANUFACTURING DEVICE

摘要

An exposure apparatus (EX) is disclosed wherein a pattern image is projected onto a substrate (W) via a projection optical system (PL) and a liquid (LQ). The projection optical system (PL) comprises an optical member (G12) which is in contact with the liquid (LQ) and a group of optical elements (MPL) arranged between the optical member (G12) and a reticle (R). A holding mechanism (HG) for the optical member (G12) and the group of optical elements (MPL) holds the optical member (G12) in such a manner that the optical member (G12) is movable relative to the group of optical elements (MPL). By having such a structure, the exposure apparatus enables to suppress deterioration of the pattern image when exposure is carried out while filling the space between the projection optical system and the substrate with the liquid.
