7 p, 1.9 MB Fabrication and replication of re-entrant structures by nanoimprint lithography methods / Kehagias, Nikolaos (Institut Català de Nanociència i Nanotecnologia) ; Francone, Achille (Institut Català de Nanociència i Nanotecnologia) ; Guttmann, Markus (Karlsruhe Institute of Technology) ; Winkler, Frank (Karlsruhe Institute of Technology) ; Fernández Estévez, Ariadna (Institut Català de Nanociència i Nanotecnologia) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia)
In this work, the authors present and demonstrate a simple method to fabricate and mass replicate re-entrant structures. The method consists of the direct imprinting of polymer mushroomlike microstructures produced by a combination of photolithography and nickel up-plating process. [...]

(Institut Català de Nanociència i Nanotecnologia) ; Morris, Michael A. (Trinity College Dublin)
Achieving ultrasmall dimensions of materials and retaining high throughput are critical fabrication considerations for nanotechnology use. This article demonstrates an integrated approach for developing isolated sub-20 nm silicon oxide features through combined "top-down" and "bottom-up" methods: nanoimprint lithography (NIL) and block copolymer (BCP) lithography.

(Institut Català de Nanociència i Nanotecnologia)
Hydrogel materials offer many advantages for chemical and biological sensoring due to their response to a small change in their environment with a related change in volume. Several designs have been outlined in the literature in the specific field of hydrogel-based optical sensors, reporting a large number of steps for their fabrication. [...]

7 p, 1.5 MB In-line metrology for roll-to-roll UV assisted nanoimprint lithography using diffractometry / Kreuzer, Martin (Institut Català de Nanociència i Nanotecnologia) ; Whitworth, Guy L. (Institut Català de Nanociència i Nanotecnologia) ; Francone, Achille (Institut Català de Nanociència i Nanotecnologia) ; Gomis Bresco, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Kehagias, Nikolaos (Institut Català de Nanociència i Nanotecnologia) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia)
We describe and discuss the optical design of a diffractometer to carry out in-line quality control during roll-to-roll nanoimprinting. The tool measures diffractograms in reflection geometry, through an aspheric lens to gain fast, non-invasive information of any changes to the critical dimensions of target grating structures. [...]
