Patent number: 10191382Abstract: 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.Type: GrantFiled: April 26, 2018Date of Patent: January 29, 2019Assignee: Carl Zeiss SMT GmbHInventors: Erich Schubert, Alexander Kohl, Gerhard-Wilhelm Ziegler, Michael Patra, Markus Deguenther, Michael Layh

Patent number: 8514371Abstract: 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.Type: GrantFiled: April 28, 2011Date of Patent: August 20, 2013Assignee: Carl Zeiss SMT GmbHInventors: Wolfgang Hummel, Juergen Fischer, Karl-Eugen Aubele, Erich Merz, Raoul Reiner, Klaus Rief, Stefan Schoengart, Markus Neumaier, Baerbel Trossbach, Ulrich Weber, Michael Muehlbeyer, Hubert Holderer, Alexander Kohl, Jochen Weber, Johannes Lippert, Thorsten Rassel
