Abstract :
An IGBT (insulated-gate bipolar transistor) is presented which is based on bulk silicon material without a buffer layer. In contrast to other devices the carrier lifetime was kept as high as possible. It is shown that such a device with a breakdown voltage of 1400 V and a short-circuit capability of 1200 V at 20 V gate voltage has on-state and switching losses that are not higher-maybe even lower- than those of a buffer layer device if its backside p-emitter efficiency is kept low enough
