Abstract

A sensor component used to measure a magnetic field strength is disclosed. In one embodiment, the sensor component contains a plurality of leads and a sensor semiconductor chip, which measures the magnetic field strength. The sensor semiconductor chip has pads on its active upper side. These pads are connected electrically to the leads. The sensor component also contains a magnet, which is attached to the leads. The sensor semiconductor chip is arranged on an upper side of the magnet. The sensor component also has a first mold compound which shares a common boundary with the sensor semiconductor chip and surrounds the sensor semiconductor chip, the magnet and parts of the lead.
