Classification: CPC G | IPC G

Claim 0:
1. A semiconductor circuit arrangement with a semiconductor substrate,
wherein the semiconductor substrate comprises an integrated Hall sensor circuit with a first terminal and a second terminal positioned opposite the first terminal, and a third terminal and a fourth terminal positioned opposite the third terminal, wherein the integrated Hall sensor circuit is configured to:
guide a Hall supply current between the first terminal and the second terminal at a first angle to a normal to a primary flat plane of the semiconductor substrate, laterally through a Hall effect region during a first clock phase, and to generate a first electrical voltage signal in the Hall effect region, wherein the first electrical voltage signal has a first dependency on a mechanical stress of the semiconductor substrate, and
guide a Hall supply current between the third terminal and the fourth terminal at a second angle that is orthogonal to the first angle, laterally through the Hall effect region during a second clock phase, and to generate a second electrical voltage signal in the Hall effect region, wherein the second electrical voltage signal has a second dependency on the mechanical stress of the semiconductor substrate, and

wherein the semiconductor circuit arrangement is configured to ascertain a specific mechanical stress component based on a combination of the first electrical voltage signal and of the second electrical voltage signal.
