Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus capable of keeping the optical element of a projection system in wet condition during substrate replacement, and to provide a device manufacturing method. SOLUTION: For example, a closing member is used to receive liquid in a liquid confinement structure while the substrate is replaced on a substrate table in an immersion lithographic apparatus. For example, a closing member displacement mechanism using a combination of one or more leaf springs and one or more electromagnets, or a combination of one or more actuators and one or more pins, or a pressure source, is employed to move the closing member to or from the liquid confinement structure. An adjustment plate is used to compensate the varying thickness of the closing member in a closing member receptacle of varying depth on different substrates. COPYRIGHT: (C)2009,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a slide assembly, which is small and rapidly movable, in a stage of lithographic equipment. SOLUTION: A stage, which moves over a table, has a region 105 that generates repellent force, and a region 115 that generates sucking force at a central portion of the repellent-force generating region 105. A hole array 116 for supplying air is formed in the repellent-force generating region, and a magnet array is formed in the suction-force generating region 115, so that a fixed interval is formed between the table and the stage.
