Abstract

In this paper a 1.2 kV, 50 A trench clustered IGBT is experimentally demonstrated in field-stop technology for the first time. Due to the optimized field stop layer design, the off-state leakage current is lower than 1 mA at 175°C. A low on-state voltage drop of 1.6 V is achieved at 150°C. The saturation current levels are effectively controlled by the self-clamping feature. Moreover, experimental results confirm that the fabricated devices exhibit dynamic avalanche-free switching performance as well as high dV/dt controllability.
