Abstract
A semiconductor apparatus includes a substrate; and a plurality of semiconductor thin films formed on said substrate, each of said semiconductor thin films having a pn-junction, and electrodes of p-type and n-type for injecting carriers to the pn-junction, wherein said semiconductor thin films are formed so that all or a part of said pn-junctions are connected serially. As different from a semiconductor thin film constituted of a single pn-junction, the light emission with the invented semiconductor apparatus is the summation of the light emission intensities of the entire pn-junctions, so that the light emitting intensity can be increased largely.
