1. A semiconductor device, comprising:

  • a semiconductor body; and

    a temperature sensor integrated in the semiconductor body, for measuring the temperature in the semiconductor body, wherein the temperature sensor has a MOS transistor and a bipolar transistor, the MOS transistor being integrated into the semiconductor body such that a subthreshold current intensity of the MOS transistor rises or falls when there is a change in the temperature to be measured, and the MOS transistor is connected to the bipolar transistor such that the subthreshold current of the MOS transistor is amplified by the bipolar transistor.
