Experimental and Theoretical Study of 4H-SiC JFET Threshold Voltage Body Bias Effect from 25 C to 500 C

This work reports a theoretical and experimental study of 4H-SiC JFET threshold voltage as a function of substrate body bias, device position on the wafer, and temperature from 25 C (298K) to 500 C (773K). Based on these results, an alternative approach to SPICE circuit simulation of body effect for SiC JFETs is proposed.
