Digital Event

Characterization of new electronic components is essential to their design and ultimately to ensure their reliability. The 7th edition of the Carac Symposium will take place on November 24, 2020 online on the IRT Nanoelec (Act & Match) webinar platform. This edition will give pride of place to the performance gains of the very large equipment available under the Nanoelec / Characterization program, at the ESRF (now the most efficient synchrotron source in the world), at the ILL (nuclear reactor dedicated to research thanks to neutrons) and CNRS/LPSC.

Speaker: Olivier Renault - CEA-Leti > Hard X-ray Photoelectron Spectroscopy (HAXPES) at the PFNC CEA-Leti

Photoemission with hard X-rays expanded over the past 15 years the field of sub-surface analysis thanks to the advent of 3rd generation synchrotron radiation facilities enabling providing to HAXPES high energy resolution, large-range depth tuning and high sensitivities, at the expense of access time and short-time scheduling. Recently, lab-scale instruments have emerged and got commercially  available. These offer interesting complementarities to synchrotron HAXPES in terms of analytical throughput and accuracy in elemental quantification. In this talk, we will provide an overview of the systems currently available, and present some case studies in the field of nanoelectronics and energy storage technologies, including comparisons with synchrotron experiments.

The increasing complexity of electronic components and technologies, as well as the diversification of materials and manufacturing processes in the More-than-Moore approach require characterization that exceeds the performance of conventional laboratory equipment. To accurately correlate the micro and nanometric characteristics of materials with the macroscopic properties of components, researchers need to gain in spatial resolution, detection capability and acquisition speed. This is why they use very specific beams of photos and neutrons from large instruments among the best in the world available on the scientific peninsula of Grenoble.
