Abstract
Static induction transistors have been demonstrated in 4H-SiC. SiC specific semiconductor processing technologies such as epitaxy, reactive ion etching, and sidewall Schottky gates were employed. Under pulsed power test conditions, 4H-SiC SITs developed a maximum output power of 225 W at 600 MHz, a power added efficiency of 47%, and a gain of 8.7 dB. Maximum channel current was 1 A/cm, and the maximum blocking voltage was 200 V
