PROBLEM TO BE SOLVED: To provide an immersion lithographic projection apparatus.SOLUTION: The immersion lithographic projection apparatus is disclosed in which an immersion liquid is enclosed between a final element of a projection system and a substrate. The use of both hydrophobic and hydrophilic layers on various elements of the apparatus is disclosed. The use can help to prevent the formation of bubbles in the immersion liquid and to reduce a residue on the elements after being immersed in the immersion liquid.
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic projection apparatus which minimizes a liquid loss from a supply system during the exposure of ends of a substrate, in liquid immersion exposure. SOLUTION: Liquid is limited by a middle plate 210 located between the liquid supply system and the substrate W. Spaces 222, 215 among the middle plate 210, a transmitted image sensor (TIS) 220, and the substrate W are also filled with the liquid 111. This procedure can be performed by two separated space liquid-supply systems via holes 230, 240, or can be performed by the same space liquid-supply system via the holes 230, 240. Therefore, both the space 215 between the substrate W and the middle plate 210, and the space 225 between the transmitted image sensor 220 and the middle plate 210 are filled with the liquid, so that both the substrate W and the transmitted image sensor can be illuminated under the same condition. A part 200 provides one or a plurality of support surfaces with the middle plate 210 which can be held at a predetermined position by a vacuum source. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a lithographic apparatus arranged with the capability to measure the polarization of radiation projected by a projection system. SOLUTION: An analyzer plate AP positioned between the projection system PL and a radiation sensor DS is illuminated with a projected beam of radiation. The analyzer plate includes two crossing regions, each of which transmits radiation with a different polarization direction. The beam of projection radiation is patterned without influencing the polarization of the beam. By patterning the beam of projection radiation so that one region receives more radiation than the other region, the radiation sensor DS is given polarization selectivity.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of highly precisely adjusting a measuring optical system of a lithographic apparatus. SOLUTION: In the lithographic apparatus, a substrate table constituted to hold a substrate is movable to transfer the substrate between a substrate measuring position and a substrate processing position. The lithographic apparatus also includes a measuring system constituted to measure at least one aspect or a characteristic of the substrate when the substrate table holds the substrate in the measuring position. The measuring system is constituted to guide at least one measuring beam and/or a field toward the front surface of the substrate. A projection system is constituted to project a patterned radiation beam onto the target of the substrate when the substrate table holds the substrate in the substrate processing position. An adjusting system is constituted to supply adjusting fluid to at least a part of the path of the measuring beam and/or the field of the measuring system to adjust the part of the path.
