Optical semiconductor apparatus

摘要

An optical semiconductor apparatus comprising an optical semiconductor device at the side of one facet of a conductive substrate, an electrical circuit device at the side of the other facet of the conductive substrate, an insulating crystal layer formed by an epitaxial growth technique between the conductive substrate and the electrical circuit device to thereby electrically isolate the electrical circuit device from the optical semiconductor device, and a wiring layer formed on the exterior surface of the insulating crystal layer to connect an electrical connection terminal of the electrical circuit device to an electrical connection terminal of the optical semiconductor device.
