Patent number: 10345710Abstract: A microlithographic projection exposure apparatus includes a projection lens that is configured for immersion operation. For this purpose an immersion liquid is introduced into an immersion space that is located between a last lens of the projection lens on the image side and a photosensitive layer to be exposed. To reduce fluctuations of refractive index resulting from temperature gradients occurring within the immersion liquid, the projection exposure apparatus includes heat transfer elements that heat or cool partial volumes of the immersion liquid so as to achieve an at least substantially homogenous or at least substantially rotationally symmetric temperature distribution within the immersion liquid.Type: GrantFiled: August 29, 2016Date of Patent: July 9, 2019Assignee: Carl Zeiss SMT GmbHInventors: Albrecht Ehrmann, Ulrich Wegmann, Rainer Hoch, Joerg Mallmann, Karl-Heinz Schuster, Ulrich Loering, Toralf Gruner, Bernhard Kneer, Bernhard Geuppert, Franz Sorg, Jens Kugler, Norbert Wabra

Patent number: 9606445Abstract: There is disclosed a lithographic apparatus provided with a spectral purity filter which may be provided in one or more of the following locations: (a) in the illumination system, (b) adjacent the patterning device, either a static location in the radiation beam or fixed for movement with the patterning device, (c) in the projection system, and (d) adjacent the substrate table. The spectral purity filter is preferably a membrane formed of polysilicon, a multilayer material, a carbon nanotube material or graphene. The membrane may be provided with a protective capping layer, and/or a thin metal transparent layer.Type: GrantFiled: July 30, 2013Date of Patent: March 28, 2017Assignee: ASML Netherlands B.V.Inventors: Vadim Yevgenyevich Banine, Arthur Winfried Eduardus Minnaert, Marcel Johannus Elisabeth Hubertus Muitjens, Andrei Mikhailovich Yakunin, Luigi Scaccabarozzi, Hans Joerg Mallmann, Kurstat Bal, Carlo Cornelis Maria Luijten, Han-Kwang Nienhuys, Alexander Marinus Arnoldus Huijberts, Paulus Albertus Maria Gasseling, Pedro Julian Rizo Diago, Maarten Van Kampen, Nicolaas Aldegonda Jan Maria Van Aerle

Publication number: 20160131980Abstract: A microlithographic projection exposure apparatus contains an illumination system (12) for generating projection light (13) and a projection lens (20; 220; 320; 420; 520; 620; 720; 820; 920; 1020; 1120) with which a reticle (24) that is capable of being arranged in an object plane (22) of the projection lens can be imaged onto a light-sensitive layer (26) that is capable of being arranged in an image plane (28) of the projection lens. The projection lens is designed for immersion mode, in which a final lens element (L5; L205; L605; L705; L805; L905; L1005; L1105) of the projection lens on the image side is immersed in an immersion liquid (34; 334a; 434a; 534a). A terminating element (44; 244; 444; 544; 644; 744; 844; 944; 1044; 1144) that is transparent in respect of the projection light (13) is fastened between the final lens element on the image side and the light-sensitive layer.Type: ApplicationFiled: September 14, 2015Publication date: May 12, 2016Inventors: Aurelian Dodoc, Karl-Heinz Schuster, Joerg Mallmann, Wilhelm Ulrich, Hans-Juergen Rostalski
