Abstract:
A semiconductor arrangement including a load transistor and a sense transistor that are integrated in a semiconductor body. One embodiment provides a number of transistor cells integrated in the semiconductor body, each transistor cell including a first active transistor region. A number of first contact electrodes, each of the contact electrodes contacting the first active transistor regions through contact plugs. A second contact electrode contacts a first group of the first contact electrodes, but not contacting a second group of the first contact electrodes. The transistor cells being contacted by first contact electrodes of the first group form a load transistor, with the second electrode forming a load terminal of the load transistor. The transistor cells being contacted by first contact electrodes of the second group form a sense transistor.
