Abstract

An integrated Hall sensor is provided with: a main wafer () of semiconductor material having a substrate () with a first surface () and a second surface (), opposite to the first surface () along a vertical axis (y); Hall sensor terminals (') arranged at least one of the first and second surfaces () of the substrate (); an isolation structure () in the substrate () defining a Hall sensor plate () of the integrated Hall sensor, the Hall sensor terminals being arranged in the isolation structure (). The integrated Hall sensor moreover has a test or calibration coil integrated in the wafer (), having a plurality of windings formed, at least in part, by metal portions () arranged above the first and second surfaces () of the substrate () and defining an inner volume () entirely enclosing the Hall sensor plate ().
