Reliability Testing for the Next Generation of Microelectronic Devices

J. Plawsky, W. Gill, M. Riley, J. Borja, and B. Williams
Rensselaer Polytechnic Institute, Troy, NY, USA

Understanding and predicting the reliability of new generations of high and low-k dielectrics is increasingly important for gate oxides and interlayer dielectrics as both films have become thinner and scaling of device operating voltages has not kept pace with the decrease in the size of ...

Numerical Modeling of Falling Aluminum Particle Oxidation in Air

A. Davidy
Israel Military Industry, Ramat-Hasharon, Israel

Because of its high enthalpy of combustion, aluminum has been added to energetic materials. In this paper, a two dimension thermal model is developed and assessed to describe the interrelated processes of Aluminum particle oxidation by using the software COMSOL Multiphysics. The thermal ...

Hydro-Mechanical Modelling of a Shaft Seal in a Deep Geological Repository

D. Priyanto
Atomic Energy of Canada Limited, Pinawa, MB, Canada

The hydro-mechanical (HM) numerical simulation of a shaft seal installed at a fracture zone in a hypothetical host rock using COMSOL is presented. Two different stages are considered in the numerical modelling. Stage 1 simulates the groundwater flow into an open shaft. Stage 2 simulates ... En savoir plus

Modification of the Ion Angular Distribution in Plasma Sheath: Modeling Approach under COMSOL Multiphysic

J. Brcka
TEL US Holdings, Albany, NY, USA

System for in-situ control of the ion angular distribution function (IADF) in plasma reactor is modeled. Typical IADF depends on the pressure, bias and excitation frequency. It is formed due to a difference in the physical properties of the plasma and sheath domains. The IADF is modified ... En savoir plus

Upgrading the HFIR Thermal-Hydraulic Legacy Code Using COMSOL

I.T. Bodey[1], R.V. Arimilli[1], and J.D. Freels [2]
[1]The University of Tennessee, Knoxville, TN, USA,
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

Modernization of the High Flux Isotope Reactor (HFIR) thermal-hydraulic (TH) design and safety analysis capability is an important step in preparation for the conversion of the HFIR core from a high enriched Uranium (HEU) fuel to a low enriched Uranium (LEU) fuel. Currently, an important ... En savoir plus

Software Package for Modeling III-Nitride QW Laser Diodes and Light Emitting Devices

M. V. Kisin[1], R. G. W. Brown[1], and H. S. El-Ghoroury[1]
[1]Ostendo Technologies, Inc., Carlsbad, CA, USA

We present a modeling software package developed at Ostendo Technologies for analysis and design of semiconductor laser and light-emitting diodes. The current database of material parameters supports complete group of III-Nitride alloys used in visible spectrum applications and can be ... En savoir plus

Hydro-Mechanical Response of Sedimentary Rocks of Southern Ontario to Past Glaciations

O. Nasir[1], M.Fall[1], T.S. Nguyen[1,2], and E. Evgin[1]
[1]Department of Civil Engineering, University of Ottawa, Ottawa, Ontario, Canada
[2]Canadian Nuclear Safety Commission (CNSC), Ottawa, Ontario, Canada

The last glacial cycle in the Northern Hemisphere started approximately 120,000 year ago. During that cycle, Southern Ontario was buried under a continental ice cap, with a maximum thickness of up to 3km. The ice cap retreated approximately 10,000 years ago. The COMSOL Multiphysics code ... En savoir plus

Electromagnetic Wave Simulation in Fusion Plasmas

O. Meneghini[1], and S. Shiraiwa[1]
[1]Plasma Science and Fusion Center, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA

COMSOL has been used to model the propagation of electromagnetic waves in fusion plasmas. For the first time, a finite element method has been used to solve the wave propagation for realistic fusion plasma parameters in the lower hybrid and ion cyclotron frequency ranges. Moreover, for ... En savoir plus

Particle Flow Control by Magnetically Induced Dynamics of Particle Interactions

F. Wittbracht[1], A. Weddemann[1], A. Auge[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

In this work, we show that dipolar magnetic coupling can be used to control the particle flow through microfluidic structures without changing the state of motion of the carrier liquid. Also no external magnetic gradient fields are employed; the total external magnetic force applied is ... En savoir plus

Chip Drop After Silver Sintering Process

M.H. Poech[1], M. Weiß[1], and K. Gruber[1]

[1]Fraunhofer Institute for Silicon Technology, Itzehoe, Germany

Since a couple of years, sintering becomes more and more important for power electronics. To press a semiconductor under high temperature in silver paste on a substrate promises benefits for durability. Tests with semiconductors of different thickness expose some problems. After the cool ... En savoir plus
