Computer Model of Cancer Development

Barjis I., Barjis J., Sayar M., Barjis I., Barjis J., Amarrai W., New York City College of Technology, US

Cancer development is a very complex process. Wide range of factors could contribute to the development of cancer. Factor that can lead to the development of cancer can range from oxygen free radicals to micronutrient [...]

Airgap and Line Slope Modeling for Interconnect

Badrieh F., Puchner H., Cypress Semiconductor, US

We have devised a generic methodology for characterizing airgaps and line slope and including those features in interconnect modeling. The method is silicon-based and can be used to accurately model the impact on capacitance. Our [...]

Statistical Simulations of Oxide Leakage Current in MOS Transistor and Floating Gate Memories

Larcher L., Pavan P., Università di Modena e Reggio Emilia, IT

The purpose of this paper is to illustrate a physically-based model allowing the statistical simulations of oxide leakage currents in MOS transistors and Floating Gate memories. This model computes the leakage current through defects randomly [...]

Compact Modeling of Four-Terminal Junction Field-Effect Transistors

Liou J., University of Central Florida, US

This paper presents a physics -based compact model for a four terminal (independent top and bottom gates) junction field-effect transistor (JFET). The model describes the JFET’s dc and ac characteristics with a high degree of [...]

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 [...]

Computational Modeling of a Piezoelectrically Actuated Microvalve for the Control of Liquid Flowrate

Saeidi S.M., Khodadadi J.M., Johnson C.A., Lee C., Yang E.H., Auburn University, US

Computational modeling of liquid flow in a piezoelectrically actuated microvalve is discussed. A 3-D structured mesh with 330,000 hexahedral cells that represents the major features of the microvalve was generated for the numerical model. Due [...]

Elastomeric Composites to Reduce the Effects of Trunnion Mode in Inertial Devices

Perez Ma., Shkel A.M., University of California Irvine, US

Composites have long been known for their ability to combine the properties of dissimilar materials to create properties ideally tailored for an application. We propose applying these features to MEMS in order to reduce the [...]

Electromechanical Modeling of MEMS Resonators with MOSFET Detection

Abelé N., Pott V., Boucart K., Casset F., Séguéni K., Ancey P., Ionescu A.M., Swiss Federal Institute of Technology of Lausanne, CH

This work reports on analytical modeling and investigation of Resonant Suspended-Gate MOSFETs (RSG-MOSFET) as future solutions for RF applications including MEMS and ICs. Pure metal-metal capacitive detection for resonators is shown to be the most [...]

Design Optimisation of an Electrostatic MEMS Actuator with Low Spring Constant for an “Atom Chip”

Rouabah H.A., Gollasch C.O., Kraft M., University of Southampton, UK

The advance of MEMS based sensors and microfabrication techniques has facilitated innovative technologies such as so-called ‘atom chips’, where a cloud of ultra cold atoms in a Bose Einstein Condensate (BEC) is controlled and manipulated [...]

MEMS Reliability Assessment ProgramMicro-electromechanical Systems (MEMS) Reliability Assessment Program for Department of Defense Activities

Zunino III J.L., Skelton D., Mason R., U.S. Army Corrosion Office, US

As the U.S. Army transforms into a lighter, more lethal force, the technologies that support both legacy and emerging weapon systems must decrease in size while increasing in intelligence. Micro-electromechanical systems (MEMS) are one such [...]
