Abstract
A Hall element is integrated on a single substrate and is capable of cancelling offset voltage with a spinning switch configured to switch spinning current and capable of simultaneously detecting a horizontal direction magnetic field and a vertical direction magnetic field. The Hall element has a four-fold rotational axis and includes a P-type semiconductor substrate layer formed of P-type silicon, a vertical magnetic field detection N-type doped region formed on the P-type semiconductor substrate layer, and eight horizontal magnetic field detection N-type doped regions formed so as to surround the vertical magnetic field detection N-type doped region.
