Embark on an exciting technological journey with CEA-Leti!

This internship offers a unique opportunity to enhance your skills in GaN power devices and develop cutting-edge architectures. You’ll work alongside a multidisciplinary team specializing in material engineering, characterization, device simulation, and electrical measurements, with the potential to transition into a PhD program. If you’re eager to innovate, expand your knowledge, and tackle state-of-the-art challenges, this position is a valuable addition to your career!

Vertical GaN power components are highly promising for power applications beyond the kV range and are therefore extensively studied worldwide. Transistors with a 'trench MOSFET' architecture have been demonstrated in the state-of-the-art with very encouraging results. The gate stack of these devices is a crucial element as it directly impacts their on-state resistance, threshold voltage, and the control signal to be applied in a power converter. The proposed study in this thesis will focus on developing innovative gate stacks that can withstand high gate voltages while maintaining state-of-the-art threshold voltage and channel mobility with minimal gate dielectric trapping. The work will involve studying the impact of process parameters on electrical characteristics. Special attention will be given to optimizing the gate geometry through TCAD simulations to study how its shape impacts on-state and breakdown. Identified improvements will be integrated to the devices fabricated on our 200mm GaN power devices line. The internship will take place within the power devices lab and supported by several ongoing projects.

With a solid foundation in microelectronics devices and a fervor for technological research, you are eager to learn, have excellent communication skills and like to work as part of a team. You are particularly interested in methodologies that merge device physics with the electrical characterization of new device architectures for power electronics.
