ABSTRACT:
A vertical Hall device includes: a substrate; a semiconductor region having a first conductive type and disposed in the substrate; and a magnetic field detection portion disposed in the semiconductor region. The magnetic field detection portion is capable of detecting a magnetic field parallel to a surface of the substrate in a case where a current flows through the magnetic field detection portion in a vertical direction of the substrate. The semiconductor region is a diffusion layer including a conductive impurity doped and diffused therein. The semiconductor region is made of diffusion layer so that the device has high design degree of freedom.
