Abstract
A semiconductor light-emitting elementincludes a silicon single crystal substratehaving a first and a second surfacesin head-tail relationship with each other, a GaN-based semiconductor laminateformed on a selected region of the first surface with a predetermined conductive intermediate layerinterposed therebetween, a first electrode layerhaving a portion in contact with an uppermost layer of the GaN-based semiconductor laminateand insulated from the monocrystal silicon substrate, and a second electrode layerformed on a suitable portion of the monocrystal silicon substrate. The monocrystal silicon substrateis formed with a light guidefor directing light emitted from the GaN-based semiconductor laminatetoward the second surface
