    Integrated Hall / Flux Concentrator Microsystems

    Abstract: The speaker gives a survey of a new class of highly sensitive single-axis and two-axis integrated Hall magnetic sensor microsystems. They are based on an integrated combination of a CMOS integrated circuit and a planar magnetic flux concentrator. The magnetic flux concentrator is made of a thick ferromagnetic layer deposited on the CMOS wafer in a post-processing step. The CMOS part of the system contains two or more conventional Hall elements positioned under the peripheries of the flux concentrator. The flux concentrator converts locally a magnetic field parallel with the chip surface into a field perpendicular to the chip surface. Therefore, a conventional Hall element can detect an external magnetic field parallel with the chip surface. Moreover, the flux concentrator provides a magnetic gain of about 10.
