Fabrication of Self Organized Copper Nanostructures on Structureless Surfaces

Kunz R., Kipp L., Skibowski M., Adelung R., Christian-Albrechts-University, DE

An easy way to cover large areas with nano-or microstructures is self-organization. Against intuition, we claim that structureless crystals in terms of surface features are well suitable for self organized structuring on the nano-and micrometer [...]

Nanostructuring of Surfaces using Anodic Alumina Masks – Methods, materials and properties

Sawitowski T., Beyer N., Wagener S., Schulz F., AlCove Surfaces GmbH, DE

Since the discovery that cleanability is not necessarily linked to smoothness or gloss of surfaces it is interesting to take a closer look at methods allowing surfaces to be structured on a micrometer and nanometer [...]

Krylov-Subspace-Based Order Reduction Methods Applied to Generate Compact Thermo-Electric Models for MEMS

Bechtold T., Salimbahrami B., Rudnyi E.B., Lohmann B., Korvink J.G., IMTEK, University of Freiburg, DE

A high power dissipation density in todays miniature electronic/mechanical systems makes on-chip thermal management very important. In order to achieve quick to evaluate, yet accurate thermo-electric models, needed for the thermal management of microsystems, a [...]

Convergence Acceleration Techniques

Jentschura U.D., Aksenov S.V., Mohr P.J., Savageau M.A., Soff G., Universität Freiburg, DE

This work describes numerical methods which are useful in many areas: examples include statistical modelling (bioinformatics, computational biology), theoretical physics, and even pure mathematics. The methods are primarily useful for the acceleration of slowly convergent [...]

Analysis and Verification of Processing Sequences

Hansen U., Triltsch U., Büttgenbach S., Germer C., Franke H-J, Institute for Microtechnology, Braunschweig, DE

In the field of micro technology new technologies are being developed and employed to generate increasingly complex microsystems. Due to this, engineers have to be acquainted with considerable knowledge about the different processing technologies in [...]

Mixed-Level Model for Highly Perforated Torsional Actuators Coupling the Mechanical, the Electrostatic and the Fluidic Domain

Sattler R., Schrag G., Wachutka G., Institute for Physics of Electrotechnology, DE

Electrostatic attraction between neighboring electrodes is a widely used actuation principle employed in tiltable micromirrors or microrelays. Electrostatic actuation is especially favored for switching applications in mobile telecommunication because of its low power consumption. State-of-the-art [...]

A Unified Environment for the Modeling of Ultra Deep Submicron MOS Transistors

Gneiting T., Advanced Modeling Solutions, DE

This paper discusses the aspects of modern MOS modeling requirements. Starting fro the fact, that even the Compact Model Council (CMC) outlined BSIM3v3 as a standard MOS simulation mode, many other models are used throughout [...]

Compact Bipolar Transistor Modeling – Issues and possible solutions

Schroter M., University of Technology Dresden, DE

Recently, several advanced compact bipolar transistor models ave become available to the design community. For existing technologies, these models (and their internal formulation) are believed to offer sufficient flexibility and accuracy, especially compared to the [...]

Merging Atomistic and Continuum Simulations of Silicon Technology – The Best from the Two Worlds

Pichler P., Fraunhofer Institute for Integrated Circuits, DE

Simulation of diffusion processes during front-end silicon process stepes needs to address a variety of highly complicated phenomena. In industrial environments, such simulations are nearly entirely based on continuum approaches. The physics entering into the [...]

Current Collapse in Tunnelling Transport through Benzene

Hettler M., Wenzel W., Wegewijs M., Schoeller H., Forschungszentrum Karlsruhe, DE

Single molecule electronic devices offer exciting perspectives for further minituarization of electronic circuits with a potentially large impact in applications. Several experiments have demonstrated the possibility to attach individual molecules to leads and to measure [...]
