Streched organic transistors maintain mobility on flexible substrates

Mihai Adrian Ionescu, Jürgen Brugger, Dimitrios Tsamados, Katrin Sidler Arnet, Andreea Veronica Savu, Nenad Cvetkovic

Two levels of aligned stencil lithography were used to fabricate pentacene thin film transistors on 12 mu m thick flexible polyimide substrates. Flexible transistors with 20 x 40 mu m(2) channels were electrically measured under strain up to 2.6%. After on ...

Heterogeneous material micro-transfer by ink-jet print assisted mould filling

Jürgen Brugger, Loïc Jacot-Descombes, Grégoire Maxime Smolik, Victor Javier Cadarso Busto, Vaida Auzelyte

A novel combination of ink-jet printing (IJP) and micro-transfer moulding (μ-TM) for high-resolution, heterogeneous material microstructuring is demonstrated. First, IJP is used to accurately fill the micro-cavities in an elastomeric mould, thus avoiding t ...

Facile fabrication of nanofluidic diode membranes using anodic aluminium oxide

Philippe Renaud, Arnaud Bertsch, Jürgen Brugger, Fabien Patrick Wildhaber, Oscar Vazquez Mena, Songmei Wu

Active control of ion transport plays important roles in chemical and biological analytical processes. Nanofluidic systems hold the promise for such control through electrostatic interaction between ions and channel surfaces. Most existing experiments rely ...

Compliant membranes improve resolution in full-wafer micro/nanostencil lithography

Jürgen Brugger, Oscar Vazquez Mena, Katrin Sidler Arnet, Andreea Veronica Savu, Luis Guillermo Villanueva Torrijo

This work reports on a considerable resolution improvement of micro/nanostencil lithography when applied on full-wafer scale by using compliant membranes to reduce gap-induced pattern blurring. Silicon nitride (SiN) membranes are mechanically decoupled fro ...

Highly inorganic titania based sol–gel as directly patternable resist for micro- and nano- structured surfaces

Jürgen Brugger, Vaida Auzelyte, Agnese Virginia Savegnago

Highly inorganic sol–gel films and patterned surfaces with up to 90% of titania were obtained by hydrolysis and condensation of Titanium(IV) isopropoxide. As a consequence of titania photocatalytic effect, the further treatment of the nanoimprint patterned ...

Biomimetic soft lithography on curved nanostructured surfaces

Jürgen Brugger, Thomas Kiefer, Valentin Flauraud, Victor Javier Cadarso Busto, Vaida Auzelyte

In this paper a nano-molding process using a nature-created master is demonstrated. The eye of night moth Agotis exclamationis having 100 nm-scale structures on a curved surface is used as biomimetic master mold from which nanostructures are replicated ont ...

Directly fabricated multi-scale microlens arrays on a hydrophobic flat surface by a simple ink-jet printing technique

Jürgen Brugger, Joo Yeon Kim

A shape-tunable approach is demonstrated for the fabrication of multi-scale polymer microlenses ([small mu ]-lenses) and microlens arrays (MLAs) using an ink-jet printing (IJP) technique. Also, the influence of the surface wetting conditions on the geometr ...

Stencil-nanopatterned back reflectors for thin-film amorphous silicon n-i-p solar cells

Christophe Ballif, Céline Pahud, Jürgen Brugger, Oscar Vazquez Mena, Andreea Veronica Savu, Mona Julia Katharina Klein, Franz-Josef Haug

We fabricated amorphous silicon n-i-p solar cells with two types of nanopatterned back reflectors using stencil lithography. One reflector type has a plasmonic grating that is embedded in the ZnO layer; the other one has a metallic grating patterned on top ...

UV-patternable polymers with selective spectral response

Jürgen Brugger, Victor Javier Cadarso Busto

We present the characterization of dyed doped/modified Epocore resist (Microresist Technology, Germany) with three commercially-available dyes (Proquimac Color, Spain). After being doped with lilac, red and yellow dyes in a 1:2500 ratio (dye:Epocore, w:w), ...

Vertically-stacked gate-all-around polysilicon nanowire FETs with sub-μm gates patterned by nanostencil lithography

Yusuf Leblebici, Jürgen Brugger, Giovanni De Micheli, Michail Zervas, Andreea Veronica Savu, Davide Sacchetto, Shenqi Xie

We report on the top-down fabrication of vertically-stacked polysilicon nanowire (NW) gate-all-around (GAA) field-effect-transistors (FET) by means of Inductively Coupled Plasma (ICP) etching and nanostencil lithography. The nanostencil is used to form sub ...

High-Resolution Resistless Nanopatterning on Polymer and Flexible Substrates for Plasmonic Biosensing Using Stencil Masks

Jürgen Brugger, Oscar Vazquez Mena, Andreea Veronica Savu, Luis Guillermo Villanueva Torrijo, Mahmut Tosun

The development of nanoscale lithographic methods on polymer materials is a key requirement to improve the spatial resolution and performance of flexible devices. Here, we report the fabrication of metallic nanostructures down to 20 and 50 nm in size on po ...

Fabrication of epoxy spherical microstructures by controlled drop-on-demand inkjet printing

Jürgen Brugger, Loïc Jacot-Descombes, Victor Javier Cadarso Busto, Rosario Maurizio Gullo

Well-controlled spherical microstructures open new possibilities for several MEMS devices, such as hemispherical microfluidic channels or micro-optical elements. However, machining of micro-spherical shapes has proven to be difficult with conventional plan ...

All-stencil transistor fabrication on 3D silicon substrates

Philippe Langlet, Cyrille Hibert, Peter Vettiger, Jürgen Brugger, Oscar Vazquez Mena, Katrin Sidler Arnet, Andreea Veronica Savu, Luis Guillermo Villanueva Torrijo, Cristina Martin Olmos

The standard lithographic techniques to fabricate electronic components involve the use of polymers, baking steps and chemicals. This typically restricts their application to flat substrates made up of standard materials. Stencil lithography has been propo ...
