ABSTRACT:
A semiconductor device for detecting or emitting a magnetic line of force or light is so provided that the major surface of its built-in semiconductor chip has a predetermined inclination angle relative to a mount surface of a mount substrate. An active layer of element for detecting a magnetic line of force or light or an element for emitting a magnetic line of force or light is formed on the major surface of the semiconductor chip. It is, therefore, possible to achieve a smaller mount thickness as defined relative to a mount surface and to detect a magnetic line of force or light coming in a direction parallel to the mount surface or to emit a magnetic line of force or light in a direction vertical to the mount surface.
