Presented is a temperature and geometry scalable 800°C Silicon Carbide (SiC) Junction Field Effect Transistor (JFET) compact device model designed to simulate the small signal effects of the SiC JFET-R process developed by NASA Glenn Research Center. With the JFET-R process pushing the temperature limits of integrated circuits, a high-fidelity device model capable of predicting the performance over temperature and geometry is required to realize the thermal ruggedness this process provides. A high temperature (HT) packaging system was utilized to characterize a SiC JFET device up to 800°C with a dwell time of 9 hours during a single test. Invaluable device characterization data was obtained and utilized to extend the device model presented to simulate SiC JFET performance continuously over 800°C.
