Load-Pull Setup Development at 185 GHz for On-Wafer Characterization of SiGe HBT in BiCMOS 55 nm Technology

Caroline Maye, Sylvie Lepilliet, Etienne Okada, Marc Margalef-Rovira, Issa Alaji, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière

This article aims to discuss challenges and performances of a passive load-pull test bench dedicated to the G-band frequencies. The first task of this work is the development of the setup to perform high power generation, impedance generation, and high-power dynamic of measurement. The solution...

Electro-Acoustic Properties of Scandium-Doped Aluminum Nitride (Sc_xAl_1-xN) Material and its Application to Phononic Crystal-Coupled SAW Devices

Fahima Arab, Fares Kanouni, Rafik Serhane, Yan Pennec, Zafer Özer, Khaled Bouamama

Within the framework of the Density Functional Theory, the elastic, dielectric, and piezoelectric coefficients of w-ScxAl1−xN material were investigated for scandium (Sc) concentrations x = 0 to 0.375. The electro-acoustic properties are used to investigate the frequency response of the SAW delay...

Picosecond acoustics versus tape adhesion test: Confrontation on a series of similar samples with a variable adhesion

A. Vital-Juarez, L. Roffi, J.-M. Desmarres, Arnaud Devos

A large number of methods have been developed to characterize the adhesion of a thin film to a substrate. Among them, tape test is still one of the most popular methods. Acoustic waves and especially ultra-high frequency acoustic waves are also sensitive to adhesion defects as they affect the way...

Low Buffer Trapping Effects above 1200 V in Normally off GaN-on-Silicon Field Effect Transistors

Idriss Abid, Youssef Hamdaoui, Jash Mehta, Joff Derluyn, Farid Medjdoub

We report on the fabrication and electrical characterization of AlGaN/GaN normally off transistors on silicon designed for high-voltage operation. The normally off configuration was achieved with a p-gallium nitride (p-GaN) cap layer below the gate, enabling a positive threshold voltage higher than...

Review on Unmanned Aerial Vehicle Assisted Sensor Node Localization in Wireless Networks: Soft Computing Approaches

Visalakshi Annepu, Deepika Rani Sona, Chinthaginjala Ravikumar, Kalapraveen Bagadi, Mohammad Alibakhshikenari, Ayman Althuwayb, Bader Alali, Bal Virdee, Giovanni Pau, Iyad Dayoub, Chan Hwang See, Francisco Falcone

Node positioning or localization is a critical requisite for numerous position-based applications of wireless sensor network (WSN). Localization using the unmanned aerial vehicle (UAV) is preferred over localization using fixed terrestrial anchor node (FTAN) because of low implementation complexity...

Modeling of access resistances and channel temperature estimation for GaN HEMT

Shariful Islam, Mohammad Abdul Alim, Abu Zahed Chowdhury, Christophe Gaquière

Accurate prediction of resistances at the transistor’s access zone and their temperature dependency are very important, since the current flow to the device depends on that region. In this paper, we have modeled the access resistances and have verified their temperature dependency with the...

La photonique dans la métropole lilloise

Laurent Bigot, Guillaume Ducournau, A. Amo

Ces dernières années, la métropole lilloise s’est imposée comme un pôle de recherche académique incontournable dans le domaine de la photonique. C’est notamment le cas des travaux en optique fibrée, en optique non-linéaire, en topologie ou encore en photonique-Terahertz, qui ont une forte...

Combination of selective area sublimation of p-GaN and regrowth of AlGaN for the co-integration of enhancement mode and depletion mode high electron mobility transistors

Thi Huong Ngo, Rémi Comyn, Sébastien Chenot, Julien Brault, Benjamin Damilano, Stephane Vezian, Eric Frayssinet, Flavien Cozette, Nicolas Defrance, François Lecourt, Nathalie Labat, Hassan Maher, Yvon Cordier

We report on the fabrication of an enhancement mode p-GaN/AlN/GaN high electron mobility transistor with selective area sublimation under vacuum of the p-GaN cap layer. The GaN evaporation selectivity is demonstrated on the thin 2 nm AlN barrier layer. Furthermore, the regrowth of AlGaN is a major...
