1.8 mΩ·cm2 vertical GaN-based trench metal–oxide–semiconductor field-effect transistors on a free-standing GaN substrate for 1.2-kV-class operation
TL;DR: In this paper, a redesigned epitaxial layer structure with a regular hexagonal trench gate layout was proposed to reduce the specific on-resistance to as low as 1.8 mΩcm2 while obtaining a sufficient blocking voltage for 1.2kV-class operation.
Journal ArticleDOI
Vertical GaN-based trench metal oxide semiconductor field-effect transistors on a free-standing GaN substrate with blocking voltage of 1.6 kV
TL;DR: In this paper, the authors reported the characteristics of vertical GaN-based trench metal-oxide-semiconductor field effect transistors on a free-standing GaN substrate with a blocking voltage of 16 kV.
Proceedings ArticleDOI
Over 10 a operation with switching characteristics of 1.2 kV-class vertical GaN trench MOSFETs on a bulk GaN substrate
TL;DR: In this article, the authors demonstrate a 1.2 kV-class vertical GaN trench MOSFET with high current and switching operations, achieving a blocking voltage of 1.3 kV by using a field-plate edge termination around an isolation mesa.
Proceedings ArticleDOI
100 A Vertical GaN Trench MOSFETs with a Current Distribution Layer
TL;DR: In this paper, a vertical GaN-based trench MOSFET with a current distribution layer (CDL) in a drift layer is employed for the high current operation.
