    摘要: A semiconductor component has a plurality of GaN-based layers, which are preferably used to generate radiation, produced in a fabrication process. In the process, the plurality of GaN-based layers are applied to a composite substrate that includes a substrate body and an interlayer. A coefficient of thermal expansion of the substrate body is similar to or preferably greater than the coefficient of thermal expansion of the GaN-based layers, and the GaN-based layers are deposited on the interlayer. The interlayer and the substrate body are preferably joined by a wafer bonding process.

    摘要: A radiation-emitting thin-film semiconductor chip with an epitaxial multilayer structure (12), which contains an active, radiation-generating layer (14) and has a first main face (16) and a second main face (18)—remote from the first main face—for coupling out the radiation generated in the active, radiation-generating layer. Furthermore, the first main face (16) of the multilayer structure (12) is coupled to a reflective layer or interface, and the region (22) of the multilayer structure that adjoins the second main face (18) of the multilayer structure is patterned one- or two-dimensionally with convex elevations (26).

    摘要: A method for producing a semiconductor component, in which a semiconductor layer is separated from a substrate by irradiation with laser pulses, the pulse duration of the laser pulses being less than or equal to 10 ns. The laser pulses have a spatial beam profile with a flank slope is chosen to be gentle enough to prevent cracks in the semiconductor layer that arise as a result of thermally induced lateral stresses during the separation of semiconductor layer and substrate.
