The scaling down of Copper interconnects is an effective approach to increasing the number of signal I/O lines and performance in advanced fine-pitch packaging. However, as dimensions are reduced, the risk of electromigration-induced failures in the copper interconnects becomes ... En savoir plus

Nowadays, designing ever more efficient power modules requires complex materials and more innovative methodologies. To significantly reduce the lead time of the devices and decrease the costs, especially during the prototyping and the testing phases, a Finite Element Analysis (FEA) can ... En savoir plus

This work, which is done in the framework of the SisAl Pilot EU project, presents the use of the COMSOL Multiphysics® software for simulating ladle furnace preheating. The SisAl Pilot project aims at optimising the silicon production in Europe by recycling materials and using a carbon ... En savoir plus

The growing adoption of electric vehicles has led to increased exposure of cars to stray magnetic fields. To address this issue, inductive position sensors have emerged as a viable solution due to their inherent immunity to stray magnetic fields. Widespread adoption of the inductive ... En savoir plus

The paper describes how the fluxgate current sensor works and how it is built in the COMSOL Multiphysics® software. Four COMSOL® modules were used: -AC/DC Module: the magnetic field physic is used in order to apply the Ampere-Maxwell’s law to the different sensor components and to the ... En savoir plus

Process Hardware for heating, etching and plasma deposition in vacuum processes on Silicon wafers or glass substrates face challenging requirements due to very shallow and extended structures. Molecular Flow calculations are used to evaluate staggered shields with the aim to protect ... En savoir plus

NDIR (Non-dispersive infrared) sensors are state of the art for measuring gas concentrations in the Mid-infrared spectrum, e.g. components of exhaled human breath. These sensors require fitting light sources. Micro light bulbs and other filament based light source are sensible to ... En savoir plus

Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... En savoir plus

The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... En savoir plus

Baking is a central production step in the industrial production of edible wafers and waffles. The initially liquid batter is heated with a pair of metallic baking plates. Establishing a uniform and accurate temperature at the baking face (inner baking plate surface) is crucial for ... En savoir plus
