All-stencil transistor fabrication on 3D silicon substrates

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

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 ...

Parallel AFM imaging and force spectroscopy using two-dimensional probe arrays for applications in cell biology

Peter Vettiger, Harry Heinzelmann, Mélanie Favre, Martha Liley, André Meister

Atomic force microscopy (AFM) investigations of living cells provide new information in both biology and medicine. However, slow cell dynamics and the need for statistically significant sample sizes mean that data collection can be an extremely lengthy pro ...

Parallel optical readout of cantilever arrays in dynamic mode

Peter Vettiger

Parallel frequency readout of an array of cantilevers is demonstrated using optical beam deflection with a single laser-diode pair. Multi-frequency addressing makes the individual nanomechanical response of each cantilever distinguishable within the receiv ...

Sub-ppm detection of vapors using piezoresistive microcantilever array sensors

Terunobu Akiyama, Peter Vettiger, Laure Aeschimann, Christoph Gerber

The performance of microfabricated piezoresistive cantilever array sensors has been evaluated using various vapors of volatile organic compounds including alkanes with different chain length from 5 (n-pentane) to 14 (n-tetradecane). We demonstrate that pie ...
