第一个演示是基于 50 µm、7×1014 cm−3 掺杂漂移层的高压 (9.2 kV) 4H-SiC 双极结型晶体管 (BJT),在 VCEO=5 V 时实现 150 A/cm2 的发射极电流密度,表明在不考虑电流扩散的情况下,特定导通电阻 (RSP_ON) 为 33 mΩ cm2,如果考虑电流扩散,则为 49 mΩ cm2。该结果远远超过了之前 4H-SiC BJT 记录的 3.2 kV(RSP_ON=78 mΩ cm2)。
The first demonstration is reported of a high-voltage (9.2 kV) 4H-SiC bipolar junction transistor (BJT) based on a 50 µm, 7×1014 cm−3 doped drift layer, achieving an emitter current density of 150 A/cm2 at VCEO=5 V, suggesting a specific on-resistance (RSP_ON) of 33 mΩ cm2 without considering current spreading or 49 mΩ cm2 if current spreading is considered. The result far exceeds the previous 4H-SiC BJT record of 3.2 kV with RSP_ON=78 mΩ cm2.
