Improvement in Turn-Off Loss of the Super Junction IGBT with Separated n-Buffer Layers

In this study, we propose a super junction insulated-gate bipolar transistor (SJBT) with separated n-buffer layers to solve a relatively long time for carrier annihilation during turn-off. This proposition improves the turn-off characteristic while maintaining similar on-state characteristics and br...
