Abstract
A semiconductor light-emitting diode includes an electrically conductive substrate transmissive to light-emitting wavelengths, and semiconductor layers including a light-emitting layer, on the substrate. A principal-surface electrode is located on the semiconductor layers and a rear-surface electrode having an opening is located on the rear surface of the substrate. The width of the opening is L, the distance between the rear-surface electrode and the light-emitting layer is t, L≦2 t, and the rear-surface electrode covers no more than 40% of the rear surface of the substrate.
