| 20090130787 | Method for fabricating a plurality of electromagnetic radiation emitting semiconductor chips - Method for fabricating a semiconductor chip which emits electromagnetic radiation, wherein to improve the light yield of semiconductor chips which emit electromagnetic radiation, a textured reflection surface is integrated on the p-side of a semiconductor chip. The semiconductor chip has an epitaxially produced semiconductor layer stack based on GaN, which comprises an n-conducting semiconductor layer, a p-conducting semiconductor layer and an electromagnetic radiation generating region which is arranged between these two semiconductor layers. The surface of the p-conducting semiconductor layer which faces away from the radiation-generating region is provided with three-dimensional pyramid-like structures. A mirror layer is arranged over the whole of this textured surface. A textured reflection surface is formed between the mirror layer and the p-conducting semiconductor layer. | 05-21-2009 |
