    摘要: PROBLEM TO BE SOLVED: To provide a reflective lighting technology that reduces an adhesion amount of particulates such as debris to the reflective surface. SOLUTION: A lighting optical device for illuminating a surface being irradiated with exposure light EL includes a lighting optical system ILS having a curved mirror 24 and a concave surface mirror 25 and forming a position substantially conjugate to the surface being irradiated between the curved mirror 24 and the concave surface mirror 25, and a second aperture board 5 separating a space B with the curved mirror 24 and a space C with the concave surface mirror 25 to different vacuum environments or decompression environments, and having an opening 5a through which the exposure light EL passes, wherein the opening 5a is arranged at a position where the cross section of the exposure light EL is smallest or in the vicinity thereof. The quantity of passing particulates such as debris can be reduced for the subsequent optical system. COPYRIGHT: (C)2009,JPO&INPIT

    摘要: PROBLEM TO BE SOLVED: To provide a lithography apparatus capable of preventing the thermal fluctuation in an optical path, for stabilizing measurement with an interferometer system. SOLUTION: A gas shower 1 of an optical device adjusts the optical path of at least one interferometer system IF. The gas shower 1 includes a gas distribution chamber 2 comprising a shower exit side that supplies gas to the optical path OP. The gas distribution chamber 2 is so configured as to spray the gas to the optical path OP. The gas distribution chamber 2 includes a substantially sharp tapered tip. COPYRIGHT: (C)2007,JPO&INPIT
