EXPOSURE APPARATUS AND DEVICE PRODUCING METHOD

摘要

In an exposure apparatus (EX), a liquid (1) is placed between a projection optical system (PL) and a substrate (P), and the apparatus (EX) exposes the substrate (P) by projecting an image of a pattern on the substrate (P) through the optical projection system (PL) and the liquid (1). The apparatus has a liquid removing mechanism (40) provided near an image surface of the projection optical system (PL) and intermittently blowing a gas to a reference member (7) and a moving mirror (55) to which the liquid (1) is adhered, removing the liquid. In projecting a pattern on a substrate through a projection optical system and a liquid and exposing the substrate, the structure above makes it possible that unnecessary liquid is removed and a desired device pattern is formed on the substrate.
