    Abstract: A multi-element sensor for measuring a magnetic field. The multi-element sensor comprises a magnetic sensing element, and an electronic circuit. The magnetic sensing element comprises a sensor substrate and a magnetic sensor. The magnetic sensing element is mounted on the electronic circuit and contact pads are provided on the magnetic sensor. The contact pads of the magnetic sensing element are electrically connected with the electronic circuit. The electronic circuit is produced in a first technology and/or first material and the magnetic sensing element is produced in a second technology and/or second material different from the first technology/material, and the contact pads are disposed next to an edge or at a corner of the sensor substrate.

    Abstract: A semiconductor chip for measuring a magnetic field based on the Hall effect. The semiconductor chip comprises an electrically conductive well having a first conductivity type, in a substrate having a second conductivity type. The semiconductor chip comprises at least four well contacts arranged at the surface of the well, and having the first conductivity type. The semiconductor chip comprises a plurality of buffer regions interleaved with the well contacts and having the first conductivity type. The buffer regions are highly conductive and the buffer region dimensions are such that at least part of the current from a well contact transits through one of its neighboring buffer regions.

    Abstract: A magnetic field sensor structure having a number of inner, outer and intermediate electrodes, arranged in a particular manner, such that groups of four electrodes can be used to form horizontal Hall elements, whereby neighboring Hall elements “share” one of the two readout electrodes. Multiple Hall elements may be biased and readout simultaneously. A modulated or unmodulated readout-technique may be used. Integrated magnetic concentrator may be added to the structure. The number of Hall elements may be odd or even. The structure can be used e.g. to measure the magnetic field of a 2-pole, 4-pole or 6-pole ring or disk magnet.
