Abstract
A semiconductor Hall element consists of a substantially rectangular main island and at least one small island of semiconductor material, one conductivity type disposed in an epitaxial semiconductor layer grown on a single crystal semiconductor substrate of the opposite conductivity type. In the main island, a pair of highly doped elongated current terminal regions of the one conductivity type are disposed, so that they are near and substantially parallel to a pair of sides of the main island, which are opposite to each other. At least a highly doped Hall signal voltage terminal semiconductor region of the one conductivity type is disposed in the small island. The Hall signal voltage terminal region has a protrusion having a small cross section, the extremity of which is slightly beyond one side of the main island which is perpendicular to the current terminal regions.
