Using Topology Derived Masks to Facilitate 3D Design

Schiek R., Schmidt R., Sandia National Laboratories, US

To accelerate MEMS design for surface micromachining applications, an algorithm and associated design tool have been created which translates designers’ 3D models into 2D lithographic production masks. Typically, designing a surface micromachined, MEMS device requires [...]

Finite Element Validation of an Inverse Approach to the Design of an Electrostatic Actuator

Juillard J., Cristescu M., Guessab S., SUPELEC, Department of Measurement, FR

We present an approach to the design of electrostatically-actuated micro-structures and discuss its implementation in a software tool called IDEA. The main advantage of this approach is that it considerably reduces problems associated to coupling [...]

Methodology for Prediction of Ultra Shallow Junction Resistivities Considering Uncertainties with a Genetic Algorithm Optimization

Renard C., Scheiblin P., de Crécy F., Ferron A., Guichard E., Holliger P., Laviron C., CEA-LETI, FR

The accurate prediction of arsenic activation after spike annealing is mandatory for Ultra Shallow Junction (USJ) sheet resistance optimization for advanced NMOS transistors engineering. For the first time, we propose a fast and efficient methodology [...]

In-Plane Micropump: Design Optimization

Sin J., Lee W.H., Stephanou H.E., RPI, US

This paper presents the fabrication, analysis and optimization of a novel monolithically fabricated diaphragm micropump, referred to as an in-plane micropump. Compared to previous technology, the micropump in this paper is fabricated to have all [...]

Biomolecule Electrostatic Optimization with an Implicit Hessian

Bardhan J.P., Lee J-H., Altman M.D., Leyffer S., Benson S., Tidor B., White J.K., Massachusetts Institute of Technology, US

Computational rational drug design is the application of computer simulation techniques to improve screening processes for new drugs or to design them de novo. The goal is to identify molecules that have high affinity and [...]

Modelling and Optimization of Medical Test Strips Made From Plastics

Peters D., Bolte H., Laur R., University of Bremen, DE

Introduction In cooperation with industrial partners, a behavioural model for the microsystem ‚Medical Test Strips‘ has been created by the authors in order to decrease cost and effort in the design process. As there is [...]

Simulation and Optimization of Tesla Valves

Truong T-Q, Nguyen N-T., Nanyang Technological University, SG

Tesla valve is a no-moving-parts valve. It has many advantages over conventional checkvalves in microscale. However, there has been very few literatures discussing its optimization. Systematic construction of the valve’s geometry has not been reported. [...]

Physically-Based Approach to Deep-Submicron MOSFET Compact Model Parameter Extraction

Chiah S.B., Zhou X., Lim K.Y., See A., Chan L., Nanyang Technological University, SG

This paper demonstrates a physically-based approach to parameter extraction of the compact Ids model we have developed for deep-submicron technology development. A two-iteration parameter-extraction scheme is described, which improves the previous one-iteration approach. Parameter calibration [...]

Optimal Design of a MEMS Relay Switch

Brenner M.P., Lang J., Li J., Qiu J., Slocum A., Harvard University, US

We describe a novel methodology for predicting optimal designs for microelectromechanical devices. The methods are applied towards the optimization of component shapes of a bistable MEMS switch. Small modifications in component shapes lead to a [...]

Actuation for Probe-Based Mass Data Storage

Alfaro J.F., Fedder G.K., Carnegie Mellon University, US

This paper describes the development of a micro media actuator (MMA) for probe-based mass data storage. The process is based on dry etching and incorporates a thinned silicon media sled to increase the frequency response [...]
