US Patent 12021139 Semiconductor arrangement with an integrated temperature sensor

A semiconductor arrangement is disclosed. The semiconductor arrangement includes: a semiconductor body and a temperature sensor (TES) integrated in the semiconductor body. The TES includes: a first semiconductor region of a first doping type arranged, in a vertical direction of the semiconductor body, between a second semiconductor region of a second doping type and a third semiconductor of the second doping type, and a contact plug ohmically connecting the first semiconductor region and the second semiconductor region. The first semiconductor region includes a base region section spaced apart from the contact plug in a first lateral direction of the semiconductor body and a resistor section arranged between the base region section and the contact plug. The resistor section is implemented such that an ohmic resistance of the resistor section between the base region section and the first semiconductor region is at least 1 MΩ.
