<p>There are disclosed two types of semiconductor devices: a semiconductor device composed mainly of one or more spherical semiconductor elements each of which is constituted by forming a photovoltaic power generating section and a pair of electrodes on a spherical semiconductor crystal and used as a semiconductor photocatalyst, a photodiode, or a solar cell; and a semiconductor device composed mainly of one or more spherical semiconductor elements each of which is constituted by forming a p-n junction and a pair of electrodes on a spherical semiconductor crystal and used as a light emitting diode, any of various kinds of diodes, or a display panel. In the semiconductor photocatalyst (1) shown in the drawing, a p-type diffusion layer (6) and a p-n junction (7) are formed in a spherical n-type silicon semiconductor crystal (2), and a micro-photocell (17) containing a photovoltaic power generating section (16), a pair of electrodes (14 and 15) faced to each other on both sides of the crystal (2), an SiO2 , film (9), and a TiO2 film (10) having a photocatalytic function are formed on the crystal (2). <IMAGE></p> |
