Abstract:
A liquid immersion lithography apparatus and method expose a substrate with an optical beam via an optical assembly and liquid by (i) arranging a stage opposite to the optical assembly such that the liquid is maintained in a local space under the optical assembly, the stage having an upper surface and a surface of a pad member and being configured to support the substrate within the upper surface; and (ii) moving the upper surface and the surface of the pad member in a movement relative to the optical assembly in a state in which the upper surface and the surface of the pad member are adjacent to and substantially coplanar with each other so that the surface of the pad member is arranged opposite to the optical assembly in place of the upper surface while the liquid is maintained in the local space under the optical assembly.

Claim (Index 14):
The method according to  claim 13 , wherein the stage and the different stage are each configured to support the substrate such that a surface of the substrate and the upper surface are substantially coplanar.
