摘要： A precision assembly (210) for positioning a device (226) includes a stage (260) that retains the device (226), a dual mover assembly (228) that moves the stage (260), and the device (226) along a movement axis (266), a measurement system (222) and a control system (224). The dual mover assembly (228) includes a first mover (262) that moves the stage (260) along the movement axis (266) and a second mover (264) that moves the device (226) along the movement axis (266). The second mover (264) is rigidly coupled to the first mover (262) so that movement of the first mover (262) results in movement of the second mover (264). Further, the total output of the dual mover assembly (228) along the movement axis (266) is equal to the sum of the movement of the first mover (262) and the movement of the second mover (264). The measurement system (222) measures a movement position along the movement axis (266). The control system (224) controls the dual mover assembly (228) utilizing the movement position. The control system (224) is designed to effectively decouple the control of the first mover (262) from the control of the second mover (264). Further, the control system (224) includes a quantization feedforward loop.

摘要： An illumination optical apparatus which illuminates an illumination objective surface with an exposure light includes: an illumination optical system having a curved mirror and a concave mirror and defining a position substantially conjugate with the illumination objective surface between the curved and concave mirrors; and a second aperture plate separating a space in which the curved mirror is arranged and a space in which the concave mirror is arranged into mutually different vacuum environments or pressure-reduced environments, and having an aperture through which the exposure light passes, the aperture being arranged at a position at which a cross-sectional area of the exposure light 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.

摘要： A reflection type illumination optical apparatus, which guides an exposure light to a reticle surface via a curved mirror, a concave mirror, etc. includes a vacuum chamber which accommodates the curved mirror, the concave mirror, etc; and a subchamber which is arranged in the vacuum chamber and which accommodates the curved mirror. The subchamber has openings through which the exposure light coming into the curved mirror and the exposure light exiting from the curved mirror pass, respectively. Each of the openings 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.

摘要： A flange portion is provided to at least a part of the periphery at the center position in the direction of the optical axis of a lens. The lens is held with clamping members and a lens holding metallic part, with the flange portion pressed by the clamping members. The portion where the flange portion is provided, suffers no compressive strain and tensile strain due to the bending of the lens, and is a part of the periphery of a neutral plane, which is the farthest plane from the optical surface of the lens. Therefore, the influence of the clamping force on the flange portion acting on other portions of the lens is reduced to the utmost, and the deformation of the optical surface due to the force acting on the flange portion is reduced to a minimum. As a result, the deterioration of the optical properties of the lens can be suppressed to the utmost.
