Semiconductor switching device and method of controlling a carrier lifetime in a semiconductor switching device |
摘要 |
A semiconductor layer, through which a main current flows, is so structured that a carrier life time in the semiconductor layer is ununiform in accordance with a predetermined distribution of the carrier life time. Thus, turn OFF characteristics of a semiconductor switching device can be improved without causing any unacceptable disadvantages for other characteristics.
