Development of Device-Level Chemical-Mechanical Polishing Simulation Module Using Cellular Automata Method

Yeh H.-M., Chen K.-S., National Cheng Kung University, TW

This work briefly presents the basic theory, the development, and a primary demonstration of a device-level chemical-Mechanical Polishing (CMP) CAD module. By integrating the phenomenological material removing relation such as Preston’s equation, contact mechanics, finite [...]

Toward an Integrated Computational Environment for Multiscale Computational Design of Nanoscale Ion Channel Semiconductors

Natarajan S., Varma S., Tang Y., Parker S., Mashl J., Jakobsson E., NCSA, US

This paper describes the design and operation of an integrated multiscale computational environment for design of nanoscale ion channel semiconductors, the Ion Channel Workbench. The present work builds on an earlier multiscale calculation from our [...]

An Interactive Website as a Tool for CAD of Power Circuits

Swiercz B., Starzak L., Zubert M., Napieralski A., Technical University of Lodz, PL

The rapid development of microelectronics results in more complex semiconductor device structures and makes it necessary to use modern computer software. However, high prices and hardware requirements considerably limit the access to these CAD tools [...]

Layout Verification by Extraction for Micro Total Analysis Systems

Baidya B., Mukherjee T., Carnegie Mellon University, US

The increasing complexity of MicroTotalAnalysis Systems is leading to a growing need for verification tools for such designs. Numerical simulation of such designs are slow, memory consuming and practically impossible for large designs. Schematic-based simulation [...]

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 [...]

Compact Modeling of Tunneling Breakdown in PN Junctions for Computer-Aided ESD Design (CAD for ESD)

Subramanian Y., Darling R.B., University of Washington, US

This paper presents compact, physically-based electrothermal models for direct as well as indirect bandgap tunneling processes in pn-junctions for use in network simulators (e.g. Saber or VHDL-A). The model for indirect tunneling has been validated [...]

An Efficient Optical Propagation Technique for Optical MEM Simulation

Kurzweg T.P., Levitan S.P., Martinez J.A., Kahrs M., Chiarulli D.M., University of Pittsburgh, US

As designers become more aggressive in introducing optical components into micro-systems, additional capabilities are required for modeling and simulation tools. Common optical modeling techniques are not applicable for most optical micro-systems, and techniques that are [...]

Mixed-Dimensionality, Multi-Physics Simulation Tools for Design Analysis of Microfluidic Devices and Integrated Systems

Przekwas A.J., Makhijani V.B., CFD Research Corporation, US

Computational design of microfluidic devices and integrated microsystems involves several strongly coupled physical disciplines, including fluid mechanics, heat transfer, stress/deformation dynam-ics, electrokinetics, biochemistry and others. CFDRC is dev

Full Wave Electromagnetic Analysis and Model Order Reduction for Complex Three Dimensional Structures

Balk I., He Y., IntelliSense Corporation, US

Progress in MEMS and packaging design has made significant changes in the requirements for modeling tools. In order to design a modern microdevice or interconnect system it is no longer sufficient to limit the analysis [...]

Compact Modeling of Avalanche Breakdown in pn-Junctions for Computer-Aided ESD Design (CAD for ESD)

Subramanian Y., Darling R.B., University of Washington, US

This paper presents and validates compact, physically-based electrothermal models of the avalanche process in pn junctions for use in network simulators (e.g. Saber). Self-heating effects are also included. This enables the simulation of large systems [...]
