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

Publication number: 20110019171Abstract: The present disclosure relates to an optical device, in particular for microlithography, having an optical module, a supporting structure and a force-generating device. The force-generating device is connected to the optical module and the supporting structure and is designed to exert a clamping force on the optical module. The force-generating device has a fluidic force-generating element having a working chamber to which a working fluid having a working pressure can be applied. The force-generating element takes the form of a muscle element which exerts a first tensile force at a first working pressure and a second tensile force which is increased with respect to the first tensile force at a second working pressure which is increased with respect to the first working pressure.Type: ApplicationFiled: March 24, 2010Publication date: January 27, 2011Applicant: CARL ZEISS SMT AGInventors: Erich Schubert, Andreas Heisler, Joachim Hartjes

Patent number: 7321126Abstract: There is provided a projection exposure system operable in a scanning mode along a scanning direction. The projection exposure system includes a collector that receives light having a wavelength ?193 nm and illuminates a region in a plane. The plane is defined by a local coordinate system having a y-direction parallel to the scanning direction and an x-direction perpendicular to the scanning direction. The collector includes (a) a first mirror shell, (b) a second mirror shell within the first mirror shell, and (c) a fastening device for fastening the first and second mirror shells. The mirror shells are substantially rotational symmetric about a common rotational axis. The fastening device has a support spoke that extends in a radial direction of the mirror shells, and the support spoke, when projected into the plane, yields a projection that is non-parallel to the y-direction.Type: GrantFiled: May 2, 2006Date of Patent: January 22, 2008Assignee: Carl Zeiss SMT AGInventors: Wolfgang Singer, Wilhelm Egle, Markus Weiss, Joachim Hainz, Joachim Wietzorrek, Johannes Wangler, Frank Melzer, Bernhard Gellrich, Bernhard Geuppert, Erich Schubert, Martin Antoni

Publication number: 20060183629Abstract: In a process for concentrating an at least partially crystalline solid containing at least one zeolite in a mixture comprising at least one auxiliary, for example a template compound, and said solid, the mixture is ultrafiltrated in a step (II) to divide the mixture into a retentate and a permeate, the solids content in the retentate being higher than that in the mixture and the solids content in the permeate being lower than that in the mixture. This procedure allows auxiliaries, in particular template compounds, present in the permeate to be recycled into a crystallizing step (I) upstream of step (II).Type: ApplicationFiled: January 28, 2005Publication date: August 17, 2006Applicant: BASF AktiengesellschaftInventors: Ulrich Muller, Hartwig Voss, Erich Schubert, Friedrich Hill, Hermann Petersen
