A Multiscale Model of Micro Cantilever Arrays

Lenczner M., Pillet E., Cogan S., Hui H., FEMTO-ST, FR

Abstract:The presentation is a contribution in the area of MEMS Array modelling. In some cases, Arrayed Microsystems present coupling between their components, and their global simulation cannot be performed taking into account individual sub-systems separately. [...]

High-Stability Numerical Algorithm for the Simulation of Deformable Electrostatic MEMS Devices

Rottenberg X., Nauwelaers B., De Raedt W., Elata D., IMEC, BE

This paper presents a novel high-stability algorithm for the simulation of the electromechanical actuation of electrostatic MEMS devices. Its stability improves on that of voltage- and charge-drive algorithms. It further offers a purely electrical simulation [...]

AC Electroosmotic Fluid Flow in Electrolytes Generated by Two Coplanar Microelectrodes

Adamiak K., University of Western Ontario, CA

AC electroosmotic pumping of fluids is studied in the model consisting of two thin coplanar electrodes, deposited on a dielectric substrate and placed in an aqueous solution. An AC voltage is supplied to the electrodes [...]

Random Dopant Induced Fluctuations of Characteristics in Deep Sub-micron MOSFETs

Chou H-M, Lo S-C, Tsai J-H, Li Y., NCHC, TW

As the gate length of MOSFET devices shrinks down below 100 nm, the fluctuation of major devices parameter, namely, threshold voltage (VTH), subthreshold swing, drain current (ID) and subthreshold leakage current duo to influences of [...]

Lab-on-a-chip technologies combine a sequence of chemical and/or biological analyses on a miniaturized platform to perform an analytical task or series of tasks. Lab-on-a-chip applications include chemical/biological agent detection, DNA sequencing/analysis, and drug discovery, to [...]

Numerical Analysis of Nano-imprinting Process Based on Continuum Hypothesis

Kim B.S., Kim H-C, Woo Y.S., Lee W.I., Oh S.I., Kim B.S., Kim H-C, School of Mechanical and Aerospace Engineering, Seoul National University., KR

Nano-imprint lithography (NIL) is a processing tech-nique capable of transferring nano-scale patterns onto a thin film of thermoplastics such as polymethyl methacrylate (PMMA). Feature sizes down to 10 nm have been demonstrated to be made [...]

Searching for a New Type of Surface Percolation on a 3D lattice

Tanizawa T., Takano H., Miyazima S., Kochi National College of Technology, JP

We consider a new surface percolation problem on a 3D simple cubic lattice through numerical simulation. In this problem, randomly occupied surfaces initially form an inﬁnite cluster at p = 0.21, where p is the [...]

Direct Numerical Simulation of Moving Charged, Flexible Bodies with Thermal Fluctuations

Patankar N.A., Northwestern University, US

The interaction of sub-micron scale objects with fluids is an important problem encountered in miniaturized systems. Various physical phenomena should be modeled simultaneously for a fundamental investigation of these systems. Our objective is to develop [...]
