Abstract:
1. A surface emitting semiconductor light-emitting diode (LED) comprising in a series one above the other: a layer of a substrate contact of a first conductivity type, a common substrate, a first barrier layer of the first conductivity type, a light-emitting active layer, a second barrier layer of a second conductivity type, a first contact layer of the second conductivity type, and surface implanted regions in the first contact layer which are electrically isolated from one another by irradiating with electric charge carriers, and a quantity of electrically conductive surface contacts for producing contact with the first contact layer, and wherein the substrate comprises a semiconductor substrate and the substrate has a first conductivity type, or the substrate is an electrically insulating substrate, or the substrate comprises a metal or a composite material, and a reflector layer of the first conductivity type is provided between the substrate and the first barrier layer, said first contact layer having at least one emitting surface via which radiation emitted by the active layer exits the LED, and the emitting surfaces are electrically and optically isolated from one another by surface implanted regions in the first contact layer which are irradiated with electric charge carriers, and wherein the areas of the layers located below the emitting surface starting from the first contact layer and proceeding as far as at least through the active layer are electrically and optically isolated with respect to areas of the layers not located below the emitting surface by means of first deep implanted regions irradiated with electric charge carriers.
