  • Patent number: 7961294
    Abstract: An imaging device in a projection exposure machine for microlithography has at least one optical element and at least one manipulator, having a linear drive, for manipulating the position of the optical element. The linear drive has a driven subregion and a nondriven subregion, which are movable relative to one another in the direction of a movement axis. The subregions are interconnected at least temporarily via functional elements with an active axis and via functional elements with an active direction at least approximately parallel to the movement axis.

  • Publication number: 20100265482
    Abstract: An illumination system of a micro-lithographic projection exposure apparatus is provided, which is configured to illuminate a mask positioned in a mask plane. The system includes a pupil shaping optical subsystem and illuminator optics that illuminate a beam deflecting component. For determining a property of the beam deflecting component, an intensity distribution in a system pupil surface of the illumination system is determined. Then the property of the beam deflecting component is determined such that the intensity distribution produced by the pupil shaping subsystem in the system pupil surface approximates the intensity distribution determined before. At least one of the following aberrations are taken into account in this determination: (i) an aberration produced by the illuminator optics; (ii) an aberration produced by the pupil shaping optical subsystem; (iii) an aberration produced by an optical element arranged between the system pupil surface and the mask plane.

  • Patent number: 7511886
    Abstract: An optical beam transformation system has a sequence of optical elements arranged along an optical axis of the optical beam transformation system and designed for transforming an entrance light distribution striking an entrance surface of the optical beam transformation system into an exit light distribution emerging from an exit surface of the optical beam transformation system by radial redistribution of light intensity. The optical elements include a transformation element causing a radial redistribution of light intensity and having a transformation surface inclined to the optical axis and causing a polarization-selective reflection of a light distribution incident on the transformation surface according to an efficiency symmetry characteristic for the transformation surface.

  • Patent number: 7170585
    Abstract: A projection exposure apparatus for microlithography has a light source, an illumination system, a mask-positioning system and a projection lens. The latter has a system aperture plane and an image plane and contains at least one lens that is made of a material which has a birefringence dependent on the transmission angle. The exposure apparatus further has an optical element, which has a position-dependent polarization-rotating effect or a position-dependent birefringence. This element, which is provided close to a pupil plane of the projection exposure apparatus, compensates at least partially for the birefringent effects produced in the image plane by the at least one lens.
