A Source and Drain Transient Currents Technique for Trap Characterisation in AIGaN/GaN HEMTs

Steven Duffy, Brahim Benbakhti, Wei Zhang, Karol Kalna, Khaled Ahmeda, Mohammed Boucherta, Nour Eddine Bourzgui, Maher, Hassan, Ali Soltani

The source/drain and gate induced charge trapping within an AlGaN/GaN high electron mobility transistor is studied, under normal device operation, by excluding self-heating effects, for the first time. Through direct measurement of current transients of both source and drain terminals, a...

Large-area femtosecond laser ablation of Silicon to create membrane with high performance CMOS-SOI RF functions

Arun Bhaskar, Justine Philippe, Matthieu Berthomé, Etienne Okada, J.F. Robillard, Daniel Gloria, Christophe Gaquière, Emmanuel Dubois

Femtosecond laser processing is a tool of increasing relevance for controlled etching of metals, semiconductors, and dielectrics with minimum collateral damage. We make use of this technique to remove silicon locally from the handler substrate of Silicon-on-Insulator (SOI) dies. By combining laser...

Ultrathin conducting polymer transducers : fabrication, characterization, and modeling, Transducteurs ultra fins à base de polymères conducteurs : fabrication, caractérisation et modélisation

Ngoc Tan Nguyen

Recently, ultrathin poly (3,4-ethylenedioxythiophene) (PEDOT) – based ionic actuators have overcome some initial obstacles to increase the potential for applications in microfabricateddevices. While microfabrication processing of trilayer actuators that involve no manual handling has been..., Récemment, les actionneurs ioniques ultra-minces à base de poly (3,4-éthylènedioxythiophène) (PEDOT) ont surmonté certains obstacles initiaux pour augmenter le potentiel d'applications dans les dispositifs microfabriqués. Bien que la microfabrication d’actionneurs à trois couches, n’impliquant...

Single mode polymer optical waveguides and out-of-plane coupling structure on a glass substrate

J.M. Boucaud, Q. Hivin, C. Durand, F. Gianesello, Davide Bucci, J.F. Robillard, Francois Vaurette, J.E. Broquin, Emmanuel Dubois

In this paper, we propose an approach to improve silicon photonics-based optical transceivers packaging capabilities thanks to an optical and electrical interposer. We demonstrate the fabrication of polymer optical waveguides, single mode at telecom wavelengths using photosensitive resists and...

Conception and fabrication of artificial neuron for bioinspired information processing, Conception et fabrication de neurones artificiels pour le traitement bioinspiré de l'information

Sara Hedayat

Current computing technology has now reached its limits and it becomes thus urgent to propose new paradigms for information processing capable of reducing the energy consumption while improving the computing performances. Moreover, the human brain, is a fascinating and powerful organ with..., Actuellement, les technologies du traitement d'information ont atteint leurs limites et il devient donc urgent de proposer de nouveaux paradigmes capables de réduire la consommation d'énergie tout en augmentant la capacité de calcul des ordinateurs. Le cerveau humain est un fascinant et...

Femtosecond pulsed laser for advanced photonic packaging

Quentin Hivin, Jean-Marc Boucaud, Flavie Braud, Cédric Durand, Frédéric Gianesello, Davide Bucci, J.F. Robillard, Jean-Emmanuel Broquin, Christophe Gaquière, Emmanuel Dubois

The purpose of the advanced applications of glass laser micromachining presented in this paper is to solve the difficulty of both electrical and optical interconnects needed in electro-optical packaging. Glass interposers constitute an innovative approach to integrate different types of...

Towards low-trapping GaN-on-silicon material system for 1200 V applications

Alaleh Tajalli, Idriss Abid, Riad Kabouche, Malek Zegaoui, Matteo Meneghini, Gaudenzio Meneghesso, Enrico Zanoni, A Nishikawa, F Medjdoub

This paper presents an assessment of a GaN-on-silicon buffer structure from the epi-wafer providerALLOS Semiconductors GmbH targeting 1200 V power applications. Epiwafers with 150 mmdiameter were grown by MOCVD on Si (111) substrates. Total GaN thickness is 7.1 µm withseveral interlayers for strain...

High resolution imaging of molecular assemblies on a semiconductor surface by non-contact AFM at low temperature

Natalia Turek, S. Godey, D. Deresmes, Thierry Melin, Judicaël Jeannoutot, Younes Makoudi, Frank Palmino, Frédéric Cherioux

We present a new concept for the fabrication of up to 1µm long polymer fibres on insulating alkali-halide substrates [1]. The novelty of our approach is that first, the chosen dimaleimide molecules (fig. a) perform a chain-like (and not a step-like) growth via a radical polymerization, second, that...

Anderson localization induced by gauge-invariant bond-sign disorder in square PbSe nanocrystal lattices

Athmane Tadjine, Christophe Delerue

ABSTRACT We study theoretically the problem of electrons moving on a two-dimensional square lattice characterized by nearest-neighbor hopping terms of constant amplitude but random sign. The original motivation came from the discovery that this “bond-sign” disorder can be present in square lattices...

Device for light-matter interaction enhancement in the full THz range for precise spectroscopy of small volume samples

Romain Peretti, Sergey I. Mitryukovskiy, Flavie Braud, Emilien Peytavit, Emmanuel Dubois, Jean-Francois Lampin

We designed, fabricated, characterized and performed the first experimental uses of a device assembling a waveguide and two antennas. The goal of our device is to confine the broadband pulse of a time-domain spectroscopy setup in the slot of the waveguide with the minimum losses and dispersion and...
