Abstract:
1. An exposure apparatus that exposes a substrate with exposure light via a liquid, comprising: an object that has a surface and that is capable of moving in a predetermined plane, the surface being in contact with the liquid; a first member to which the object faces and between which and the surface of the object the liquid is held; and a second member that moves in a space between the first member and the object and that can form a space to hold the liquid between the first member and the second member, wherein the object and the second member move in a direction substantially parallel to the predetermined plane in order to switch a hold of the liquid from between the first member and one of the object and the second member to between the first member and the other one of the object and the second member, wherein, in at least a part of the switching, a relative speed between the object and the second member is other than zero.
