Abstract
A rod-shaped semiconductor device having a light-receiving or light-emitting function is equipped with a rod-shaped substrate made of p-type or n-type semiconductor crystal, a separate conductive layer which is formed on a part of the surface of the substrate excluding a band-shaped part parallel to the axis of the substrate and has a different conduction type from the conduction type of the substrate, a pn-junction formed with the substrate and separate conductive layer, a band-shaped first electrode which is formed on the surface of the band-shaped part on the substrate and ohmic-connected to the substrate, and a band-shaped second electrode which is formed on the opposite side of the first electrode across the shaft of said substrate and ohmic-connected to the separate conductive layer.
