ABSTRACT:
An MOS transistor has a gate electrode is electrically conductively connected to an exposed contact area (pad). The contact area is electrochemically corrosion-resistant and is dimensioned for connection to a living cell. The surface topology is relatively flat and the surface, with the exception of the contact area, is protected with a dielectric passivation layer.
