Abstract:
1. A method for manufacturing a magnetic sensor module having magnetic sensor elements monolithically integrated at a semiconductor chip which comprises an integrated circuit, the method comprising providing a composite semiconductor arrangement comprising (i) the semiconductor chip, (ii) contact elements for the integrated circuit, which are formed on the semiconductor chip, and (iii) a dielectric layer formed over the semiconductor chip and over the contact elements, forming a magnetic sensor layer by providing the material for the magnetic sensor elements monolithically over the dielectric layer, exposing the contact elements by removing a part of the dielectric layer which part is located above the contact elements, and forming an electric conductive protection layer over either the formed magnetic sensor layer or the exposed contact elements in order to prevent negative interactions between (i) the step of forming the magnetic sensor elements resulting from the magnetic sensor layer and (ii) the step of exposing the contacting elements.
