曝光装置和曝光方法以及器件制造方法
摘要：
一种曝光装置，在投影光学系统(PL)与基片(P)之间的至少一部分用液体(50)充满，同时经由投影光学系统(PL)将图案像投影到基片(P)上对基片(P)进行曝光。对作为在移动基片(P)时与液体(50)接触的部分的光学元件(60)以及镜筒(PK)，实施调整与液体(50)的亲和性的表面处理。从而就防止了在投影光学系统与基片之间的液体中产生气泡，而且液体被经常维持在投影光学系统与基片之间，所以形成良好的浸液状态。
摘要（英）：

In an exposure apparatus, an exposure of a substrate (P) is carried out by filling at least a portion of the space between a projection optical system (PL) and the substrate (P) with a liquid (50) andprojecting the image of a pattern onto the substrate (P) via the projection optical system (PL). An optical element (60) and a barrel (PK), which are in contact with the liquid (50) when the substrate (P) is moved, are surface-treated for adjusting the affinity with the liquid (50). Consequently, generation of bubbles in the liquid between the projection optical system and the substrate is suppressed and the liquid is always retained between the projection optical system and the substrate, thereby creating a good immersion state.
