Abstract:
1. A vertical hall sensor comprising: a substrate of semiconductor material; a well doped for a conductivity type and provided as a sensor region, the well being arranged below an upper side of the substrate; a cover layer arranged to delimit a region having the conductivity type of the well in a direction toward an upper side of the substrate; and at least five contact areas arranged spaced apart from one another, arranged in the cover layer and separated by intervals, each of said at least five contact areas being doped for the same conductivity type as the well, penetrating the cover layer and forming electrical connections from the well to the upper side; wherein at least three of the at least five contact areas separated from one another by further ones of said contact areas being configured for application of an operating voltage that supplies current through said sensor region; and wherein the further ones of said contact areas being configured for tapping a hall voltage.
