摘要

The Bipolar Mode Field Effect Transistors (BMFETs) using P{sup}+ gates on N-type Silicon substrate are the most commonly used power devices for high-current medium-power switching applications and as optically controlled switches [1,2]. These are dual gate devices with deep P{sup}+ gate junctions, which require large thermal cycles for diffusion. In this paper, we propose a novel Schottky-gate BMFET (SBMFET) using P-type 4H Silicon-Carbide [3,4], a wide bandgap material, in which the PN junction gates are replaced by the Schottky gates. We have studied the characteristics of this device using two-dimensional numerical simulation [5]. Our results demonstrate for the first time that the P-SiC Schottky-gate BMFET has very low ON voltage drop, good output characteristics, a reasonable current gain and a blocking voltage greater than 1000 V.
