Abstract:
The vertical Hall element includes: a semiconductor layer of a second conductivity type formed on a semiconductor substrate of a first conductivity type; a first electrode set formed in a surface of the semiconductor layer and including a first drive current supply electrode, a Hall voltage output electrode, and a second drive current supply electrode aligned along a straight line extending in a first direction in this order; and second to fifth electrode sets each having the same configuration as the configuration of the first electrode set and aligned with the first electrode set along a straight line extending in a second direction perpendicular to the first direction. The Hall voltage output electrode has a first depth, the first and second drive current supply electrodes have a second depth that is larger than the first depth.
