摘要:
A method for producing a thin-film semiconductor body is provided. A growth substrate is provided. A semiconductor layer with funnel-shaped and/or inverted pyramid-shaped recesses is epitaxially grown onto the growth substrate. The recesses are filled with a semiconductor material in such a way that pyramid-shaped outcoupling structures arise. A semiconductor layer sequence with an active layer is applied on the outcoupled structures. The active layer is suitable for generating electromagnetic radiation. A carrier is applied onto the semiconductor layer sequence. At least the semiconductor layer with the funnel-shaped and/or inverted pyramid-shaped recesses is detached, such that the pyramid-shaped outcoupling structures are configured as projections on a radiation exit face of the thin-film semiconductor body.
