The Immersed Surfaces Technology for Reliable and Fast Setup of Microfluidics Simulation Problems

Icardi M., Caviezel D., Lakehal D., ASCOMP GmbH, CH

ASCOMP has developed a new fully automatized version for microfluidics applications in bio-devices, using the IST (Immersed surfaces Technique) technique to map complex components/geometries into a simple rectangular Cartesian grid. Near wall regions are treated [...]

Structure Generation for the Numerical Simulation of Nano-Scaled MOSFETs

Kernstock C., Karner M., Baumgartner O., Gehring A., Holzer S., Kosina H., Global TCAD Solutions, AT

An accurate and predictive numerical simulation of MOS transistor in the deca-nanometer channel length regime relies on the precise mapping of the physical device into a simulation model. A quick and accurate method which allows [...]

First self-consistent thermal electron- phonon simulator

Vasileska D., Raleva K., Goodnick S.M., Arizona State University, US

We have developed the first self-consistent thermal electron-phonon simulator which solves the Boltzmann transport equation for the electrons and the energy balance equations for phonons, and as such allows us to make realistic estimates on [...]

Simulation of Field-Plate Effects on Lag and Current Collapse in GaN-based FETs

Itagaki K., Nakajima A., Horio K., Shibaura Institute of Technology, JP

Two-dimensional transient analyses of field-plate GaN MESFETs and AlGaN/GaN HEMTs with a semi-insulating buffer layer have been performed in which a deep donor and a deep acceptor are considered in the buffer layer. Quasi-pulsed I-V [...]

Test ASIC for Real Time Estimation of Chip Temperature

Szermer M., Kulesza Z., Janicki M., Napieralski A., Technical Univiversity of Lodz, PL

The main goal of this paper is to present in detail the design and operation of an ASIC, which will be used in the research aimed at the development of a real time temperature monitoring [...]

Anomalous Thermomechanical Softening-Hardening Transitions in Micro-oscillators

Sahai T., Bhiladvala R., Zehnder A., Cornell University, US

This work documents and explains a counter-intuitive nonlinear phenomenon, where the laser-detected resonant motion of forced, micromechanical oscillators can be tuned from softening to hardening by increasing the laser power incident on a prestressed silicon [...]

Modeling and Design of Electrostatic Voltage Sensors Based on Micromachined Torsional Actuators

Dittmer A., Dittmer J., Dittmer A., Dittmer J., Judaschke R., Büttgenbach S., Technische Universität Braunschweig, DE

The optimization of design parameters and methods for electrostatic voltage sensors based on torsional actuators is presented. The analytical software model used for this optimization process is discussed and compared to measurement results. Voltage excitation [...]

The static behavior of RF MEMS capacitive switches in contact

Suy H.M.R., Herfst R.W., Steeneken P.G., Stulemeijer J., Bielen J.A., NXP Semiconductors Research, NL

A method is presented in which surface topography characterization is combined with the electrical measurement of the contact mechanics under electrostatic loading. Contact characteristics such as the surface separation versus the applied pressure, and the [...]

Bulk-Titanium Waveguide – a New Building Block for Microwave Planar Circuits

Huang X.T., Todd S., Ding C., MacDonald N.C., University of California at Santa Barbara, US

We present a new topology for planar microwave transmission line: bulk titanium waveguide. The waveguide is formed by deep trench etching, dielectric gap filling, and planarization. The high aspect ratio of the resulting structure provide [...]

Towards an efficient multidisciplinary system-level framework for designing and modeling complex engineered microsystems

Clark J.V., Zeng Y., Jha P., Purdue University, US

We present advances in designing and modeling complex microsystems at the network/system-level. For design, we develop a graphical user interface that allows users to quickly configure complex systems in 3D using a computer mouse or [...]
