Integrierte Hall-Effekt-Anordnung

摘要

An integrated Hall-effect device is described in which a part of a semiconductor body serves as a Hall element and in which an amplifier circuit is incorporated in the remaining part, which semiconductor body is connected to conductors and is incorporated in an envelope of synthetic material. The envelope at the area of the lower and upper side of the Hall element contains recesses extending to the proximity of the semiconductor body in which poleshoes of a ferromagnetic material can be incorporated in order to concentrate the magnetic field at the Hall element.
