EXPOSURE APPARATUS AND METHOD FOR PRODUCING DEVICE

摘要

An exposure apparatus EX includes a recovery port which recovers a liquid, a blow port which is provided outside the recovery port with respect to an optical path space and which blows a gas therefrom, and a gas discharge port which is provided between the recovery port and blow port and which discharges at least a part of the gas blown from the blow port. An exposure apparatus which makes it possible to avoid the leakage of the liquid with which the optical path space of the exposure light between a projection optical system and a substrate is filled is provided.
