Abstract

A semiconductor circuit is disclosed which contains a driving circuit which is integrated into a semiconductor substrate of a first conductivity type and includes positive voltage switching transistors for switching positive and/or zero voltage levels and negative switching transistors for switching negative and/or zero voltage levels. In addition, the driving circuit contains a control circuit which is positioned upstream from the driving circuit and is also embodied in the semiconductor substrate, which is connected to a substrate voltage. A negative voltage switching transistor of the driving circuit is configured inside an outer well which is embedded in the semiconductor substrate and is of a second conductivity type which is opposite to the first, and the outer well is connected to a supply voltage.
