Journal ArticleDOI
Cost-effective CMOS-compatible grating couplers with backside metal mirror and 69% coupling efficiency.
Wissem Sfar Zaoui,Maria Felix Rosa,Wolfgang Vogel,Manfred Berroth,Jörg Butschke,Florian Letzkus +5 more
TL;DR: A highly efficient grating structure for the coupling between standard optical fibers and single-mode waveguides in the silicon-on-insulator platform realized in a CMOS fabrication process is presented.
Patent
Large-area membrane mask and method for fabricating the mask
Butschke Joerg,Ehrmann Albrecht,Haugeneder Ernst,Kamm Frank-Michael,Florian Letzkus,Hans Loschner,R. Springer +6 more
TL;DR: In this article, a second wafer made of the material of the membrane layer is provided in addition to a first wafer to increase the rigidity of a membrane mask that can be used for ion projection lithography.
Proceedings ArticleDOI
Impact of EUV mask pattern profile shape on CD measured by CD-SEM
Uwe Dersch,Arnd Korn,Cornelia Engelmann,C. G. Frase,Wolfgang Haessler-Grohne,Harald Bosse,Florian Letzkus,Joerg Butschke +7 more
TL;DR: In this article, the authors used a Monte Carlo model to simulate the SEM-signals emerging from a given EUV mask pattern topography while scanned by the electron beam of a SEM.
Proceedings ArticleDOI
Charged particle multi-beam lithography evaluations for sub-16nm hp mask node fabrication and wafer direct write
Elmar Platzgummer,Christof Klein,Peter Joechl,Hans Loeschner,Martin Witt,W. Pilz,Joerg Butschke,Michael Jurisch,Florian Letzkus,Holger Sailer,Mathias Irmscher +10 more
TL;DR: In this article, a detailed evaluation study has been performed with respect to the suitability of projection electron and ion multi-beam illumination for the fabrication of leading-edge complex masks.
Proceedings ArticleDOI
Comparative evaluation of e-beam sensitive chemically amplified resists for mask making
Mathias Irmscher,Dirk Beyer,Joerg Butschke,Chris Constantine,Thomas Hoffmann,Corinna Koepernik,Christian Krauss,Bernd Leibold,Florian Letzkus,Dietmar Mueller,Reinhard Springer,Peter Voehringer +11 more
TL;DR: In this paper, positive tone chemically amplified resists CAP209, EP012M (TOK), KRS-XE (JSR), and FEP171 (Fuji) were evaluated for mask making.
