Abstract: Wide-bandgap GaN-based power transistors and rectifiers are promising enablers for high-efficiency power conversion and energy management systems, owing to the superior fundamental material properties. Currently, there is worldwide effort in commercializing lateral GaN-based heterojunction devices grown on low-cost and highly scalable Si substrates (i.e. GaN-on-Si platform) and manufactured with existing low-cost Si fabrication lines. The main focus of technology development has been on improving process robustness and uniformity, and improving device reliability and stability.
In this talk, I will present several new techniques in GaN-on-Si power device technology, including 1) new channel design for low on-resistance and gate recess robustness; and 2) photon pumping for enhanced dynamic performance.
