[1] Fluorine-Based Plasma treatment for AlGaN/GaN E-Mode HEMTs and Low On-Voltage Diodes 44th Workshop on Compound Semiconductor Devices and Integrated Circuits held in Europe (WOCSDICE 2021), pages. 4 pages, 06/2021, URL, Abstract FORNASIERO Quentin, DEFRANCE Nicolas, LESECQ Marie, FRAYSSINET Eric, CORDIER Yvon, CHEVALIER Florian, IDIR Nadir, DEJAEGER Jean-Claude |
The onset and pinch-off voltages shift of lateral GaN field-effect rectifier diodes (L-FER) and normally-off HEMTs are studied. It is shown that a short duration of low power SF6 plasma followed by a low temperature annealing permits to get an effective and stabilized fluorine ions deposition on the AlGaN barrier, contributing to reduce the back shift of both devices threshold voltages. |
[2] Electrothermal Modeling of GaN Power Transistor for High Frequency Power Converter Design 2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe), Lyon, France, 2020, pp. 1-10, doi: 10.23919/EPE20ECCEEurope43536.2020.9215782., 09/2020, URL, Abstract PACE Loris, CHEVALIER Florian, VIDET Arnaud, DEFRANCE Nicolas, IDIR Nadir, DEJAEGER Jean-Claude |
This work proposes the electrothermal modeling of a packaged GaN power transistor in order to evaluate by simulation its performances in a 200 W – 1 MHz DC/DC converter. The complete electrical modeling of the high frequency converter using EM-circuit co-simulations is presented. After validation of the GaN transistor switchings waveforms and estimation of power losses, the operating temperature of the device is simulated and experimentally validated. |
