A Basic Property of MOS Transistors and its Circuit Implications

Vittoz E., Enz C., Krummenacher F., Swiss Center for Electronics & Microtechnology, CH

The MOS transistor drain current is the (linear) superposition of independent and symmetrical effects of source and drain voltages. This basic property is not affected by the geometry or symmetry of the transistor, by the [...]

Electromechanical Modeling of MEMS Resonators with MOSFET Detection

Abelé N., Pott V., Boucart K., Casset F., Séguéni K., Ancey P., Ionescu A.M., Swiss Federal Institute of Technology of Lausanne, CH

This work reports on analytical modeling and investigation of Resonant Suspended-Gate MOSFETs (RSG-MOSFET) as future solutions for RF applications including MEMS and ICs. Pure metal-metal capacitive detection for resonators is shown to be the most [...]

Towards Nano Mechanical Sensors

Hierold C., ETH Zürich, CH

This paper is about the impact of scaling on the system performance of mechanical inertia sensors and first activities towards nano mechanical sensors. Permanent cost pressure will result in continuous efforts to integrate more functions [...]

Converting of Nanoparticles in Industrial Product Formulations: Unfolding the Innovation Potential

Schaer S., Arnosti G., Pilotek S., Tabellion F., Naef H., Buhler AG, CH

Potential users of nanoparticles want the particles in a ready-to-use form. The market currently offers practically only raw materials and standard nanoparticles not tailored to a specific application. A newly developed chemo-mechanical converting process for [...]

Integrated Optical Profiler and AFM: a 3D Metrology System for Nanotechnology

Jobin M., Du A., Foschia R., University of Applied Sciences, CH

A versatile 3D metrology tool for nanotechnology purpose has been built. It consist of an home-made white-light interferance microscope operating in the vertical scanning mode, integrated into a commercial Atomic Force Microscope. The performance in [...]

Adhesive and Conductive – Inkjettable Nano-filled Inks for use in Microelectronics and Microsystems Technology

Meyer E.M., Meyer W., Arp A., Calderone F., Kolbe J., Meyer E.M., Meyer W., Schaefer H., Stuve M., Metalor Technologies SA, CH

The present work demonstrates feasibility of an inkjettable, isotropically electrically conductive adhesive in the form of a silver loaded resin with a 2-step curing mechanism. In the first step, the adhesive is dispensed (jetted) and [...]

Flame Made Nanoparticles for Gas Sensors

Mädler L., Pratsinis S.E., Sahm T., Gurlo A., Barsan N., Weimar U., University of California, Los Angeles, CH

Flame aerosol technology is one of the most widely used synthesis routes in manufacturing of commercial quantities of nanoparticles. The application of flame spray pyrolysis further broadens the spectrum of flame made powders and their [...]

Superparamagnetic Iron Oxide Nanoparticles for Multiple Biomedical Applications

Hofmann H., Hofmann M., Petri-Fink A., Steitz B., von Rechenberg B., Hofmann H., Hofmann M., Juillerat J., Swiss Federal Institute of Technology Lausanne, CH

Superparamagneticiron oxide nanoparticles (SPION) were mixed at various ratios with different polymer solutions to obtain SPION coated with PVA modified by functional groups (amino-SPION, carboxy-SPION, and thiol-SPION). Studying human melanoma cells by theses different functionalized [...]

Peptidic Nanoparticles for Cancer Therapy and Diagnosis

Graff A., Tropel D., Raman SK., Machaidze G., Lustig A., Burkhard P., University of Basel, CH

Somatostatin peptides such as somatostatin 28 or 14 are known for their high binding affinity to G-coupled peptide receptors, which are often over-expressed on tumor cells. Using this binding property we developed a new type [...]

Peptide Based Nanoparticles as a Platform for Vaccine Design

Raman S.K., Kao D.J., Tropel D., Graff A., Machaidze G., Hodges R.S., Burkhard P., Biozentrum, CH

To-date vaccines for many of the dreadful diseases such as Tuberculosis, Malaria, AIDS and Hepatitis are still ineffective or unavailable. Peptide based vaccines have been developed but because of their poor immunogenic response and the [...]
