An integrated circuit including a semiconductor device is disclosed. One embodiment provides a load current component, having a multiplicity of trenches in a cell array. A sensor component is integrated into the cell array of the load current component and has a sensor cell array, the area of which is smaller than the area of the cell array of the load current component by a specific factor. The trenches forming the cell array of the sensor component correspond to the trenches of the cell array of the load current component, configured such that the trenches of the sensor component at the at least one side merge uniformly into the trenches of the cell array of the load current component without interruptions or disturbances of the trench geometry.
