Notes:
We have investigated the field limiting ring (FLR) geometry dependence of breakdownvoltage characteristics for a junction barrier Schottky (JBS)-assisted FLR SiC-SBD. The SiC-SBDshaving a guard ring-assisted FLR surrounding a Schottky contact edge and an internal ring insideSchottky contact were fabricated. The breakdown voltage characteristics of the JBS-assisted FLRSiC-SBD are significantly dependent on the width, spacing, and number of FLR. The breakdownvoltage characteristic is improved as either the FLR width and FLR number increase or the FLRspacing decreases. Approximately 1650 V maximal breakdown voltage, corresponding to 82% idealbreakdown voltage, is observed with seven FLRs having 5 2m width and 1 2m spacing
