    摘要: A method for micropatterning a radiation-emitting surface of a semiconductor layer sequence for a thin-film light-emitting diode chip. The semiconductor layer sequence is grown on a substrate. A mirror layer is formed or applied on the semiconductor layer sequence, which reflects back into the semiconductor layer sequence at least part of a radiation that is generated in the semiconductor layer sequence during the operation thereof and is directed toward the mirror layer. The semiconductor layer sequence is separated from the substrate by means of a lift-off method, in which a separation zone in the semiconductor layer sequence is at least partly decomposed in such a way that anisotropic residues of a constituent of the separation zone, in particular a metallic constituent of the separation layer, remain at the separation surface of the semiconductor layer sequence, from which the substrate is separated. The separation surface—provided with the residues—of the semiconductor layer sequence with a dry etching method, a gaseous etchant or a wet-chemical etchant, wherein the anisotropic residues are at least temporarily used as an etching mask. A semiconductor chip is produced according to such a method.

    摘要: A thin-film LED comprising an active layer (7) made of a nitride compound semiconductor, which emits electromagnetic radiation (19) in a main radiation direction (15). A current expansion layer (9) is disposed downstream of the active layer (7) in the main radiation direction (15) and is made of a first nitride compound semiconductor material. The radiation emitted in the main radiation direction (15) is coupled out through a main area (14), and a first contact layer (11, 12, 13) is arranged on the main area (14). The transverse conductivity of the current expansion layer (9) is increased by formation of a two-dimensional electron gas or hole gas. The two-dimensional electron gas or hole gas is advantageously formed by embedding at least one layer (10) made of a second nitride compound semiconductor material in the current expansion layer (9).
