Abstract:
An exposure apparatus is equipped with a fine movement stage that can hold a liquid with a projection optical system when the stage is at a position facing an outgoing surface of the projection optical system, and a blade that comes into proximity within a predetermined distance of the fine movement stage when the fine movement stage is holding the liquid with the projection optical system, and moves along with the fine movement stage while maintaining the proximity state, and then holds the liquid with the projection optical system after the movement. Accordingly, a plurality of stages will not have to be placed right under the projection optical system interchangeably, which can suppress an increase in footprint of the exposure apparatus.
