Toward Smart Probes for mmW On-Wafer Measurements: Advanced Packaging Using Laser Micromachining of Glass

Maya Alawar, Victor Fiorese, Sylvie Lépilliet, Daniel Gloria, Guillaume Ducournau, Emmanuel Dubois

This article introduces the development of groundsignal-ground (GSG) probes for on-wafer active measurements, fabricated using femtosecond laser micromachining with a resolution between 5 and 10 µm. The probes are made from a 100 µm-thick Schott AF32 glass substrate bonded to a 10 µm-thick nickel…

Effect of High Temperature RF Stress on the Trapping Behavior of Carbon Doped AlN/GaN/AlGaN HEMTs

Lyes Ben-Hammou, François Grandpierron, Elodie Carneiro, Katir Harrouche, Etienne Okada, Gilles Patriarche, Farid Medjdoub

This study investigates the impact of short-term hightemperature operating life (HTOL) reliability testing on the trapping behavior and power performance of carbon-doped AlN/GaN/AlGaN High Electron Mobility Transistors (HEMTs). HTOL stress can lead to significant degradation in key performance…

A Universal Implementation Approach for Multivalued Logic Gates Based on Negative Transconductance in Series-Connected Two-Dimensional Transistors

Guangchao Zhao, Wanting Wen, Keyi Liao, Philippe Coquet, Xingli Wang, Mingqiang Huang, Beng Kang Tay

Multiple-valued logic (MVL) is highly desired for algebra, logic, and artificial intelligence due to its higher information density. However, its practical adoption has been hindered for decades by extensive hardware requirements. Two-dimensional (2D) materials with exceptional electronic…

Novel Diffuse Midline Glioma‐on‐Chip Recapitulating Tumor Biophysical Microenvironment to Assess the Heterogeneity of Response to Therapies

Lisa Terrassoux, Calypso Hazard, Agathe Laratte, Joanne Balsamelli, Mélanie Arcicasa, Elisa Fong, Léo Baland, Fabrice Soncin, Giovanni Cappello, Claude‐alain Maurage, Sebastien Janel, Antony Bazir, Fabrizio Cleri, Anthony Treizebre, Eric Lartigau, Yousr Rekik, Samuel Meignan, Alessandro Furlan

Despite significant efforts, Diffuse Midline Gliomas (DMGs) remain incurable. Although promising results are obtained in preclinical studies, most approaches have failed to improve survival in these young patients. In this context, by integrating elements of the biophysical tumor microenvironment…

Brain‐Inspired Polymer Dendrite Networks for Morphology‐Dependent Computing Hardware

Corentin Scholaert, Yannick Coffinier, Sébastien Pecqueur, Fabien Alibart

Process variation is always a challenge to mitigate in electronics. This especially holds true for organic semiconductors, where reproducibility concerns hinder industrialization. Challenging this concept, it shows AC-electropolymerization to be a powerful platform for the development of morphology…

Nonlinear modeling of AlN/GaN HEMT accounting for self-biasing effect during RF step stress: analysis and hard-SOA

Nasri Said, Damien Saugnon, K. Harrouche, F Medjdoub, N. Labat, N. Malbert, Jean-Guy Tartarin

In this study, we investigate the non-linear (NL) behavior of AlN/GaN HEMT technologies under gain compression when submitted to 10 GHz single-tone RF-step stress, which is crucial for millimetre-wave power application robustness. We evaluate AlN/GaN transistors, targeting high-power amplifiers…
