Semiconductor component which can be controlled by the field effect

摘要

An IGBT (Isolated Gate Bipolar Transistor) continuously requires a control voltage in the switched-on state. This can be avoided by the semiconductor body (1) having a further zone (7) on the source side, which zone (7) is of the same conductance type as the base zone (5). This zone (7) is connected to the gate electrode (10). In consequence, the switched-on IGBT remains switched on even after the gate voltage has been disconnected. It can be disconnected by the zone (7) and the gate electrode (10) being connected to source potential. <IMAGE>
