The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map the tab to establish its thermal mapping. This led us to perform simulations at each ASIC of the tab that ...

Silicon wafers represent key elements in modern microelectronics or photovoltaics. Technological fabrications of wafer sizes with large diameters (e.g. 450 mm) allow an efficient realization for integrated circuits at low cost. However, this material shows a high sensitivity to vibrations that strongly depends on size and the positioning as well as orientation of a wafer in a mounting, realized ...
Modification of the Ion Angular Distribution in Plasma Sheath: Modeling Approach under COMSOL Multiphysic
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 by biased grid which is built into a holder. The time varying E-field in sheath is influencing the ion path. ...

In the paper, first a basic concept of the engineering approach for modeling and control of distributed parameter systems (DPS) based on interpretation of controlled systems as lumped input and distributed output systems (LDS) is introduced. Next, FEM modeling of temperature fields in casting mould and extruder body as real DPS by means of the software environment COMSOL Multiphysics® is ...

The formation of space charge clouds is a well known problem that affects thermionic emitters in regimes of high current emission. Although some analytical models have been presented, suitable for 1D geometries, the modeling of the problem in complex 3D structures remains a challenge due to the mutual coupling between electron trajectories and field they produce. Here we propose a model able to ...

In this paper, we present a 2D axisymmetric self-consistent plasma fluid model for microwave plasmas operating in argon. The model was developed using COMSOL Multiphysics and its Plasma Module. Plasma, flow, heat and electromagnetic equations solved self-consistently. The effect of the pressure on the plasma parameters is studied over a wide range of pressures going from 10 mbar to ...

Recently, electrokinetic flows have raised the interest of the scientific community. Driving flow with an electric field leads to promising applications for mixing, concentration, pumping application in lab on chips. However, current models are still inaccurate and don\'t fit the measures. The simple decoupled model developed by Ramos et al does not predict velocities for all parameters. ...

The purpose of this work is to show whether an important difference in Lithium solid concentration and electrolyte concentration can be observed in a Lithium-ion battery model, when considering either the Butler-Volmer kinetics or the Tafel kinetics for describing the electrode kinetics (including a boundary layer between the electrolyte and the electrode particles). During discharge, the ...

We have simulated alignment and movement of multiple particles under Dielectrophoresis (DEP) using the Particle Tracing Module in COMSOL Multiphysics® software with particle-particle interaction taken into consideration. We are able to do efficient modeling for both 2D and 3D cases. With this work, we are able to shed important insights into the process of pearl chain formation, antenna-like ...

Measurement of three dimensional, three component velocity fields is central to the development of effective micromixers for bioassays and lab-on-chip mixing applications. We present a hybrid experimental-numerical method for the generation of 3D flow information from 2D particle image velocimetry (PIV) experimental data and finite element simulations. An optimization algorithm is applied to a ...
