Here, we show that silicon carbide (SiC) complementary logic gates composed of p- and n-channel junction field-effect transistors (JFETs) fabricated by ion implantation operate at 623 K with a supply voltage as low as 1.4 V. The logic threshold voltage shift of the complementary JFET (CJFET) inverter is only 0.2 V from 300 to 623 K. Furthermore, temperature dependencies of the static and dynamic characteristics of the CJFET inverter are well explained by a simple analytical model of SiC JFETs.
