Project description
High-efficiency electronic devices based on gallium nitride
Gallium nitride (GaN) is a wide-bandgap semiconductor used for high-efficiency power transistors and integrated circuits. The first GaN power electronic devices have demonstrated disruptive performance and reduction of the form factor. GaN-based high electron mobility transistors allow innovative designs for space applications. Reducing the inductive parasitics and optimising the inductive passive components are key to unlocking the potential of this technology. The EU-funded EleGaNT project aims to demonstrate a higher level of integration between GaN and integrated circuits. The project will demonstrate improved designs of GaN integrated circuits and passive devices and of point-of-load convertor boards.
Objective
Discrete GaN power electronic devices have penetrated the consumer market and first products have amply demonstrated a disruptive improvement of the performance and reduction of the form factor.
With demonstrated robustness for heavy ion radiation and neutron radiation, p-GaN enhancement mode HEMTs allow disruptive innovative designs for space applications.
However, to unlock the full potential of the technology for point of load convertors, three important limitations need to be solved, as addressed in this project, i.e.
1) the reduction of the inductive parasitics through monolithic integration of drivers and power devices (GaN-IC)
2) optimization of the inductive passive components together with the active devices
3) a strong interaction between point of load convertor design and GaN-IC design.
Electrical performance and radiation robustness will be evaluated and assessed for space applications in the upcoming frame of satellites massive digitalization.
The project with duration of 36 months, comprises of two learning cycles in definition and refinement of the application requirements, design and manufacturing of the GaN-ICs and passive devices, and development of the point of load convertor boards, first with focus on the basic building blocks and initial prototypes, followed by further optimization towards the target requirements.
The consortium has been joined by Thales Alenia Space (France and Belgium) and Würth Elektronik as space and terrestrial point of load convertor manufacturers. IMEC contributes with its state-of-art GaN-IC platform technology and Würth Elektronik with the design and prototype manufacturing of the passives. MinDCet designs the optimized GaN-ICs and contributes with a state-of-art controller.
This project contributes to EU non-dependence of GaN technology as discrete GaN transistors are, so far, mostly produced by Asian and/or North American manufacturers and pushes the state-of-the-art with higher level of integration (GaN-IC).
