Abstract
A semiconductor device includes a semiconductor substrateof a first conductivity type, a vertical Hall elementprovided on the semiconductor substrate, and an excitation conductorprovided directly above the vertical Hall elementwith an intermediation of an insulating film. The vertical Hall elementincludes a semiconductor layerof a second conductivity type provided on the semiconductor substrate, and a plurality of electrodesthrougheach constituted from a high-concentration second conductivity type impurity region and provided on the surface of the semiconductor layeralong a straight line. A ratio W/Wbetween a width Wof the excitation conductorand a width Wof each of the plurality of electrodesthroughsatisfies 0.3≤W/W≤1.0.
