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 [...]

Computational Prototyping of an RF MEMS Switch using Chatoyant

Bails M., Martinez J.A., Levitan S.P., Avdeev I., Lovell M., Chiarulli D.M., University of Pittsburgh, US

In this paper we demonstrate the capabilities of our system-level CAD tool, Chatoyant, to model and simulate an RF MEMS switch. Chatoyant is a mixed signal, multi-domain CAD tool that can be used to design [...]

Modeling of the Dielectrophoretic Forces Acting upon Biological Cells: A Numerical Comparison between Finite Element/Boundary Element Maxwell Stress Tensor Methods and Dipole Point Approach

Benselama A., Pham P., Canot É., CEA, FR

Maxwell Stress Tensor (MST) method is investigated in this study to quantify the degree of approximation made with the point dipole method in respect to dielectrophoresis (DEP) in microdevices. Latex particles and biological cells immersed [...]

Development of an Advanced Simulation System for the Analysis of Particle Dynamics in LASER based Protein Ion Sources

Hieke A., Ciphergen Biosystems, Inc., US

An advanced multi-physics simulation system henceforth referred to as GEMIOS (Gas and Electromagnetic Ion Optical Simulator) has been implemented which allows the computation of 3D trajectories and energy exchange of ion beams/clouds under the influence [...]

A Fully Coulpled Computational Model of the Silylation Process

Winters W.S., Evans G.H., Prantil V.C., Larson R.S., Sandia National Laboratories, US

This paper describes a fully coupled computational model of the positive tone silylation process. The model is two-dimensional and transient and focuses on the part of the lithography process in which crosslinked and uncrosslinked resist [...]

Heat Transfer Macromodels for MEMS Devices with 3D Geometries

Yu C-C, Yang Y-J, National Taiwan University, TW

There are numerous heat transfer applications in MEMS, such as thermal actuating, uncooled infrared sensing, chip cooling, temperature sensing, PCR, and so on. Most of the applications need feedback loops for precise control or actuation, [...]

Optimization of Thermally Actuated Bimorph Cantilevers for Maximum Deflection

Peng W., Xiao Z., Farmer K.R., New Jersey Institute of Technology, US

Theoretical analysis of thermally actuated bimorph cantilevers is presented to find the optimum condition for maximum deflection. The relations between material properties, dimensions and deflections are discussed in detail to understand the mechanism. Optimum condition [...]
