摘要：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 asemiconductor chip. The semiconductor chip has an epitaxially produced semiconductorlayer stack based on GaN, which comprises an n-conducting semiconductor layer, a p-conducting semiconductor layer and an electromagnetic radiation generating regionwhich is arranged between these two semiconductor layers. The surface of the p-conducting semiconductor layer which faces away from the radiation-generating region isprovided with three-dimensional pyramid-like structures. A mirror layer is arranged overthe whole of this textured surface. A textured reflection surface is formed between themirror layer and the p-conducting semiconductor layer.
