1. A light-emitting or light-receiving semiconductor device comprising:

  • a roughly spherical semiconductor element formed from one of a p-type and a n-type semiconductor, said semiconductor element being formed with parallel first and second flat surfaces at ends on either side of a center thereof;

    a diffusion layer formed on a surface section of said semiconductor element including said first flat surface;

    a roughly spherical pn junction formed on said diffusion layer; and

    first and second electrodes disposed on said first and said second flat surfaces respectively and connected to ends of said pn junction.
