    摘要: A radiation-emitting semiconductor component having a semiconductor body (1), which has an active zone (2), in which, for the purpose of electrical contact connection, a patterned contact layer (3) is applied on a surface of the semiconductor body. Interspaces (4) are distributed over the contact layer (3) and are provided for the purpose of forming free areas (5) on the surface which are not covered by the contact layer (3). The free areas (5) are covered with a mirror (6). The separation of the two functions of contact connection and reflection makes it possible to achieve a particularly high performance of the component.

    摘要: A method is provided for fabricating a useful layer containing at least one semiconductor layer, in which the useful layer is separated from a carrier. In this case, the useful layer is applied to the carrier and an auxiliary carrier is applied to that side of the useful layer that is remote from the carrier by a connecting layer at a joining temperature. Afterward, the carrier is stripped away at a temperature that is greater than or equal to the joining temperature and is less than the melting point of the connecting layer. At least a part of the useful layer together with the auxiliary carrier is removed from the carrier.

    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.
