A novel 600 and 1200 V IGBT (insulated-gate bipolar transistor) family has been developed for operation at more than 20 kHz with sufficient ruggedness. It was found that turn-off loss can be reduced by optimizing the n/sup -/ layer thickness as well as the n/sup +/ buffer impurity profile. A thick n/sup -/ layer was found to be an important factor in improving device ruggedness. Turn-off loss was successfully reduced to one-third of that in conventional IGBTs, while a large safe operating area was retained.<<ETX>>
