Abstract

Section titled ā€œAbstractā€

Abstract 400 metal-oxide-semiconductor field-effect transistors (MOSFETs) were fabricated on a half-inch diamond substrate. The performance of each device was evaluated, and an H-terminated diamond MOSFET chip was created by connecting over 300 of the well performing MOSFETs in parallel, resulting in a gate width of 32 cm. This chip was used for double pulse testing, with its switching characteristics being evaluated at 2.5 A. The results show a fall/rise time of 19/32 ns, respectively, and switching losses during turn-off/turn-on of 4.65/1.24 Ī¼J. This study demonstrated switching operation at large currents in diamond power MOSFETs.
