Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a lithographic apparatus in which liquid can be drained through a gap between, for example, an edge of an object and a substrate table on which the object is set. SOLUTION: The liquid immersion lithographic apparatus has a drain formed for draining the liquid through the gap between an edge of a substrate and the substrate table on which the substrate is supported. The drain is provided with a means which feeds the liquid to the drain irrespective of a position of the substrate table and/or a means which saturates gas in the drain. These means reduce fluctuation in heat loss due to evaporation of the liquid in the drain. COPYRIGHT: (C)2009,JPO&INPIT |
