Abstract:
1. An exposure apparatus comprising: a projection optical system which projects an image of a pattern onto a substrate through a liquid to successively expose a plurality of shot areas on the substrate; and a liquid supply system which supplies the liquid from a first supply port arranged on one side of a projection area of the projection optical system to form a liquid immersion area on a part of the substrate including the projection area, wherein: the liquid supply system continuously supplies the liquid from the first supply port during a continuous period in which an exposure process is performed for the plurality of shot areas on the substrate, the plurality of shot areas includes a first shot area which is exposed while moving the substrate in a first direction and a second shot area which is exposed while moving the substrate in a second direction opposite to the first direction, and the plurality of shot areas are successively exposed in the continuous period without stopping the liquid supply from the first supply port on the one side of the projection area.
