Abstract:
1. A vertical Hall sensor, which is integrated in a semiconductor chip, having an electrically conductive well of a first conductivity type, which is embedded in an electrically conductive region of a second conductivity type, and having electrical contacts, which are arranged along a straight line on a planar surface of the electrically conductive well, which extends parallel to a surface of the semiconductor chip accessible for the wiring, the electrically conductive well having a doping profile generated by ion implantation and not by an epitaxy method, wherein the doping profile either has a maximum which is located at a depth T from the planar surface of the electrically conductive well, or is essentially constant or is wavy and is approximately constant averaged over the waves up to a depth T, with the depth T being T>0.
