Abstract: A semiconductor device includes a semiconductor substrate, having an excitation circuit for applying an excitation signal, and a soft-magnetic component for guiding magnetic flux lines. The soft-magnetic component is electrically connected to the excitation by at least two electrical contacts in the form of back contacts or side contacts. The substrate further includes at least one electromagnetic transducer operatively connected to the soft-magnetic component. The excitation circuit includes a modulator for providing a modulated signal to the soft-magnetic component to modulate its magnetic permeability. The substrate further has a demodulator configured to demodulate signals obtained from the at least one electromagnetic transducer.

Abstract: A sensor device including a semiconductor substrate having an excitation circuit and a sensing circuit for measuring a magneto-impedance effect of a soft-magnetic component arranged on top of the semiconductor substrate. The soft-magnetic component is operatively connected to the excitation circuit and the sensing circuit, and is electrically connected to at least one of the excitation circuit and the sensing circuit by means of back contacts or side contacts. The soft-magnetic component has an elongated shape or an elongated portion extending in a first direction parallel to the semiconductor substrate; a processing circuit connected to the sensing circuit, and configured for providing a signal indicative of the measured impedance or a value derived therefrom. A method is provided for producing such a semiconductor substrate.
