IDEA, a CAD Tool for the Design of Deformable Micro-Structures: Extension to the 2D Deformation of Arbitrarily-Shaped Membranes

A method for solving design problems involving coupled-field physics is presented: it is demonstrated in the case of the electrostatic actuation of a deformable micro-mirror. The focus of the present paper is on the inversion [...]

FE-Simulations as a Part of a Tolerance Management System

Straube D., Germer C., Franke H-J, Triltsch U., Büttgenbach S., Technical University Braunschweig, DE

This paper reports on a software tool, which enabled tolerance management based on FE-Simulations and want to deliver impressions of the benefits of this coupling. The term tolerance management unites analysis, i.e. investigation of effects [...]

A Method for Adding Static External Forcing to Invariant Manifolds

Grinde C., Westby E.R., Vestfold University College, NO

We present a new method for applying quasi-static forcing to invariant manifolds without breaking its invariance. This is usefull for modeling biased reduced-order models. The results from initial simulations are very promising and examples spesific [...]

Modeling of the Cosmic Radiation-Induced Failure Mechanism in High Power Devices

Kaindl W., Soelkner G., Schulze H.-J., Wachutka G., Institute for Physics of Electrotechnology, DE

In order to achieve a more robust design of semiconductor power devices with enhanced hardness against cosmic radiation we have been working on a physical model which is able to explain and to visualize the [...]

Boundary Integral Solution of Quasi-Linear Laplace Equation

Ding J., Ye W., Georgia Institute of Technology, US

An Integral approach based on the p-FTT acclerated BEM, which requires only surface discretization, has been developed for solving nonlinear equations. Examples of a Helmholtz and a quasi-linear Laplace problems in both a spherical domain [...]

MEMS Pressure Sensor with Two Thin Film Piezoelectric Read-Out

Sun B., Zhang R., Cape Penisula University of Technology, SA

MEMS accelerometers using piezoelectric lead zirconate titanate (PZT) thin films as read-out have been attracting a great deal of attention due to their simple structures and high sensitivity. This paper proposes a model of micro [...]

Three-Dimensional Transient Electro-Thermal Interconnect Simulation for Stress and Electromigration Analysis

Holzer S., Hollauer Ch., Ceric H., Wagner S., Entner R., Langer E., Grasser T., Selberherr S., Vienna University of Technology, AT

We introduce the combination of three-dimensional transient electro-thermal interconnect simulations for intrinsic thermo-mechanical stress problems. In order to study the development of thermal stresses we use a finite element simulator for the investigation on stresses [...]

Combination of Analytical Models and Order Reduction Methods for System Level Modeling of Gyroscopes

Schneider P., Reitz S., Bastian J., Schwarz P., Döring C., Maute M., Neul R., Fraunhofer Institute for Integrated Circuits, DE

Within complex sensor systems different physical effects and electronics for signal processing have to be considered in the design process. In this paper we describe an approach for system level simulation of sensor systems and [...]

Design of Experiment Tools for Process and Device Development

Olij N., Bakker A.F., Nutt A.C.G., PhoeniX BV, NL

The functionality of Micro and Nano Technologies (MNT) device is mainly defined by its shape; for instance a membrane sensitivity to pressure depends on its size and thickness. An MNT device therefore needs a multi [...]

Electromechanical Model for a Single Port Nano-Mechancial Beam Resonator

Kemp T., Docker P.T., Ward M.C.L., Jones I.P., The University of Birmingham, UK

A simple electromechanical model for a nano-mechanical, magneto-motively driven beam resonator is derived. The model is developed in order to determine the dynamic electrical properties of the resonator. This enables the pickoff and drive electronics [...]
