    • A target positioning device, in particular for a lithography system, comprising a carrier (300) for carrying a target, and a stage for carry¬ ing and moving the carrier a long a first direction (X). The stage com¬ prising two X-stage bases (401, 402), both arranged on top of a com¬ mon base plate (403), each X-stage base carries an X-stage carriage (404, 405), and a Y-beam (406) comprising a Y-stage (407) for carry¬ ing said carrier and moving the carrier in a second direction (Y). The Y-beam bridges the space between the X-stage carriages and is con¬ nected to the X-stage carriages via a flexible coupling (408, 409). The device further comprises two motors (Ml, M2) each for driving a cor¬ responding X-stage carriage along its corresponding X-stage base. The two motors are arranged at least substantially below the stage. Each motor of said two motors is coupled to an eccentric cam or crank (410, 411) which is connected to the corresponding X-stage carriage via a crank shaft (412, 413).
    • 特别是用于光刻系统的目标定位装置,包括用于承载目标的载体(300)和用于沿第一方向(X)移动载体的载物台。 两个X级基座(401,402)均布置在一个基板(403)顶部,每个X级基座都装有一个X级托架(404,405),并且 Y形梁(406)包括用于承载所述载体并沿着第二方向(Y)移动所述载体的Y级(407)。 Y型梁桥接X级滑架之间的空间,并通过柔性联轴器连接到X级滑架(408,409)。 该装置还包括两个电动机(M1,M2),每个电动机用于沿其相应的X级基座驱动对应的X档架。 这两个电动机至少在平台的下方布置。 所述两个电动机的每个电动机联接到偏心凸轮或曲柄(410,411),所述偏心凸轮或曲柄经由曲轴(412,413)连接到对应的X档架。

    • An illumination optical apparatus which illuminates an illumination objective surface with an exposure light EL includes: an illumination optical system ILS having a curved mirror 24 and a concave mirror 25 and defining a position substantially conjugate with the illumination objective surface between the mirrors 24 and 25; and a second aperture plate 5 separating a space B in which the curved mirror 24 is arranged and a space C in which the concave mirror 25 is arranged into mutually different vacuum environments or pressure-reduced environments, and having an aperture 5a through which the exposure light EL passes, the aperture 5a being arranged at a position at which a cross-sectional area of the exposure light EL is smallest, or in the vicinity of the position. It is possible to decrease the amount of passage of minute particles such as debris in relation to any downstream-side optical system.
    • 用曝光用光EL照明照明物镜面的照明光学装置具备:照明光学系统ILS,其具有弯曲镜24和凹面镜25,并且限定与镜子24和25之间的照明物镜表面基本共轭的位置; 以及分离其中布置有曲面镜24的空间B的第二孔板5和其中凹面镜25布置在相互不同的真空环境或减压环境中的空间C,并且具有孔5a,曝光 光EL通过,孔5a布置在曝光光EL的横截面积最小的位置或位置附近。 相对于任何下游侧光学系统,可以减少诸如碎屑的微小颗粒的通过量。

    • A reflection type illumination optical apparatus, which guides an exposure light EL to a reticle surface Ra via a curved mirror 24, a concave mirror 25, etc. includes a vacuum chamber 1 which accommodates the curved mirror 24, the concave mirror 25, etc,; and a subchamber 4D which is arranged in the vacuum chamber 1 and which accommodates the curved mirror 24. The subchamber 4D has openings 4Da, 4Db through which the exposure light EL coming into the curved mirror 24 and the exposure light EL exiting from the curved mirror 24 pass, respectively. Each of the openings 4Da, 4Db is arranged in the vicinity of a position at which the cross-sectional area of the light flux is smallest. It is possible to decrease the amount of adhesion of minute particles such as debris to the reflecting optical element, without unnecessarily enhancing the ability of the vacuum gas discharge mechanism.
    • 通过曲面镜24,凹面镜25等将曝光用光EL引导到标线片表面Ra的反射型照明光学装置包括容纳曲面镜24,凹面镜25等的真空室1, ; 以及设置在真空室1中并容纳曲面镜24的子室4D。子室4D具有开口4Da,4Db,来自弯曲反射镜24的曝光光EL和从曲面镜出射的曝光光EL 24通,分别。 每个开口4Da,4Db布置在光束的横截面积最小的位置附近。 可以在不必要地增强真空气体排出机构的能力的情况下,将诸如碎屑的微小颗粒附着到反射光学元件上。
