Abstract A 10kV-level silicon carbide (SiC) insulated gate bipolar transistor (IGBT) with field limiting rings (FLRs) is designed and simulated with Sentaurus TCAD, the detailed optimization method and comparisons are presented in this paper. Linearly varying spacing between rings is introduced to SiC IGBT and adjustment is performed on width of rings, the final structure achieves a breakdown voltage over 12kV with a termination length of 164.5 µm , which is 69.93% lower than that of conventional structure with a fixed ring spacing. Moreover, the final design can decrease the sensitivity to the interface charges, the tolerance to positive surface charges exceeds 8 × 10 11 cm − 2 , which is 3.5 times that of the conventional structure. Besides, double pulse measurements prove no degradation of conduction and switching characteristics.

Insulated gate bipolar transistor (IGBT) element is an electrically conductive device with Bipolar junction transistor (BJT) output and Metal Oxide Silicon Field Effect Transistor (MOSFET) input. The IGBTs is a power semiconductor device that aims for high breakdown voltage, low on-state voltage, fast switching and reliability. This paper is, the experiment was conducted with a two-step field stop, IGBT instead of a traditional one step field stop. In order to minimize the energy loss caused by the trade-off relationship between breakdown voltage and the on-state voltage drop, the experiment was conducted by forming a two-step field stop. Through concentration control between steps, breakdown voltage, On-state Voltage drop and turn off time could be adjusted in detail, and efficient characteristic values could be obtained accordingly. Experiments have confirmed that the On state voltage drop and turn-off time, in particular, can be adjusted by small failure voltage loss upon change in the first stage field stop.
