    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: Semiconductor chip which emits electromagnetic radiation, and method for fabricating it. To improve the light yield of semiconductor chips which emit electromagnetic radiation, a textured reflection surface (131) is integrated on the p-side of a semiconductor chip. The semiconductor chip has an epitaxially produced semiconductor layer stack (1) based on GaN, which comprises an n-conducting semiconductor layer (11), a p-conducting semiconductor layer (13) and an electromagnetic radiation generating region (12) which is arranged between these two semiconductor layers (11, 13). The surface of the p-conducting semiconductor layer (13) which faces away from the radiation-generating region (12) is provided with three-dimensional pyramid-like structures (15). A mirror layer (40) is arranged over the whole of this textured surface. A textured reflection surface (131) is formed between the mirror layer (40) and the p-conducting semiconductor layer (13). The textured reflection surface (131) can increase the amount of light which is decoupled at the radiation-outcoupling surface (111) by virtue of the fact that a beam (3), after double reflection on the reflection surface (131), is more likely not to be totally reflected.

    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.
