Patent ID: 8760629

Claim:
An exposure apparatus that exposes an object with an energy beam via a liquid, the apparatus comprising: a first movable body which is movable at least along a two-dimensional plane; an optical member which has an outgoing plane that emits the energy beam; a holding member which is movably supported by the first movable body, holds the object and is movable at least within a plane parallel to the two-dimensional plane facing the outgoing plane, and also can hold the liquid with the optical member when located at a position facing the outgoing plane; a position measurement system which has a measurement member, extending in a first axis direction parallel to the two-dimensional plane, where at least a part of a head is provided that irradiates at least one measurement beam from below on a measurement plane placed on a surface substantially parallel to the two-dimensional plane of the holding member and receives a light of the measurement beam from the measurement plane, and which measures positional information of the holding member within the two-dimensional plane, based on an output of the head; and a movable member which becomes proximal to the holding member within a predetermined distance in the first axis direction parallel to the two-dimensional plane when the holding member holds the liquid with the optical member, and moves from one side of the first axis direction to the other side along the measurement member with the holding member while maintaining the proximal state, and holds the liquid with the optical member after the movement.
