Abstract:
1. An exposure apparatus that exposes an object with an energy beam via an optical system and a liquid, the apparatus comprising: a detection system that is placed in a second area different from a first area where the optical system is placed, and detects positional information of the object; a base member of which surface is placed substantially parallel to a predetermined plane in a predetermined area that includes the first area and the second area; a delivery portion arranged in at least one of the first and the second movable bodies and capable of holding a liquid immersion area to which the liquid is supplied under the optical system; wherein the planar motor system moves the first and the second movable bodies in a second direction, which intersects a first direction in the predetermined plane, with respect to the liquid immersion area, with at least a part of the delivery portion being positioned between the upper surfaces of the movable bodies, the upper surfaces having edges placed facing each other substantially parallel to the first direction in the predetermined plane, and with one of the movable bodies being placed under the optical system, so that the movement causes the other of the movable bodies to be placed under the optical system in place of the one of the movable bodies and the immersion area to be transferred from the one of the movable bodies to the other via the delivery portion while being maintained under the optical system, and a positional relation between the first and the second movable bodies in the first direction during the movement with respect to the liquid immersion area is different for a replacement of the first movable body by the second movable body and for a replacement of the second movable body by the first movable body.
