Abstract :
The electrical characteristics of 2.5 kV-100 A μ-stack IGBTs having Punch-Through (PT) and Non-Punch-Through (NPT) types of device structures have been experimentally investigated. By optimizing the p + collector layer of the NPT type IGBT, the trade-off relationship between the saturation voltage and the turn-off energy can be obtained to fit on the curve of the PT type IGBT. The Reverse Biased Safe-Operating-Areas (RBSOAs) of the PT type and NPT type IGBTs fabricated are also very wide having a large turn-off capability of 800 A at the DC bath voltage of 1250 V
