Abstract
A semiconductor device includes a semiconductor substrate of a first conductivity type, and a vertical Hall element provided on the semiconductor substrate. The vertical Hall element includes an impurity diffusion layer of a second conductivity type and three or more electrodes. The impurity diffusion layer is provided on the semiconductor substrate and has an impurity concentration which increases as a depth increases. The three or more electrodes are provided in a straight line on a surface of the impurity diffusion layer and are composed of an impurity region of the second conductivity type having a higher concentration than the impurity diffusion layer.
