0.2-μm InP/GaAsSb DHBT power performance with 10 mW/μm² and 25% PAE at 94 GHz

Mohammed Zaknoune, Etienne Okada, Estelle Mairiaux, Yannick Roelens, Damien Ducatteau, Peter Frijlink, Marc Rocchi, Hassan Maher

We report a 94-GHz large-signal load-pull characterization of InP/GaAsSb double heterojunction bipolar transistors. The investigated devices have an emitter area of 0.20 × 9.5 μm2. Biased for highest power added efficiency (PAE), an output power of 6.62 mW/μm2 (11 dBm), a power gain of 5.2 dB, and…

A Novel Dog-Bone Oscillating AFM Probe with Thermal Actuation and Piezoresistive Detection

Zhuang Xiong, Estelle Mairiaux, Benjamin Walter, Marc Faucher, Lionel Buchaillot, Bernard Legrand

In order to effectively increase the resonance frequency and the quality factor of atomic force microscope (AFM) probes, a novel oscillating probe based on a dog-bone shaped MEMS resonator was conceived, designed, fabricated and evaluated. The novel probe with 400 μm in length, 100 μm in width and…

Electrical and chemical studies on Al2O3 passivation activation process

Matthieu Pawlik, Jean-Pierre Vilcot, Mathieu Halbwax, D. Aureau, A. Etcheberry, A. Slaoui, T. Schutz-Kuchly, R. Cabal

Passivation process is a key feature to improve the efficiency of silicon solar cells. So far, a 20nm-thick layer of Al2O3 grown by Plasma Enhanced Atomic Layer Deposition (PE-ALD) followed by a 450°C anneal during 15 to 30 min gives the best results in surface carrier recombination velocities on p…

Source localisation in a reverberant plate using average coda properties and early signal strength

Hossep Achdjian, Emmanuel Moulin, Farouk Benmeddour, Jamal Assaad, Lynda Chehami

A statistical reverberation model based on the average distribution of wave packets propagating in a finite plate is described and it is shown that by fitting experimental data to theoretical expressions, either structural or source-related features can be extracted with very few sensors. An…

Elastic properties of tensile nitrogen-plasma-treated multilayer silicon nitride films

M. Braccini, F. Volpi, Arnaud Devos, G. Raymond, D. Benoit, Pascal Morin

Highly stressed silicon nitride thin films are used in gate first complementary metal oxide semiconductors to improve mobility in the silicon channel. Compressive stresses improve hole mobility in p-type MOS transistors while tensile stresses increase electron mobility in n-type MOS devices. High…

Digital radio frequency signal generation towards ultimate transmitters

Antoine Frappé

This invited paper exposes our latest developments in the field of digital transmitters by focusing on digital and mixed-signal processing blocks, such as delta-sigma modulators, high-speed interpolation filters and digital-to-RF converters. The goal is to demonstrate that radio-frequency signal…

Coherent THz communication at 200 GHz using a frequency comb, UTC-PD and electronic detection

Guillaume Ducournau, Y. Yoshimizu, S. Hisatake, F. Pavanello, Emilien Peytavit, Mohammed Zaknoune, T. Nagatsuma, Jean-Francois Lampin

A coherent terahertz (THz) link at 200 GHz, with a variable data rate up to 11 Gbit/s, featuring a very high sensitivity at the receiver, is investigated. The system uses a quasi-optic unitravelling carrier photodiode (UTC-PD) emitter and an electronic receiver. The coherent link relies on an…
