1. An electromagnetic radiation generating semiconductor chip comprising:

  • a first set of layers including a radioparent, electrically conductive growth substrate and a semiconductor layer sequence for generating electromagnetic radiation grown on a first main face of the growth substrate;

    a radiation-diffusing structure provided on a main face of the first set of layers, wherein the electromagnetic radiation emitted to the radiation-diffusing structure from said semiconductor layer sequence is scattered by said radiation-diffusing structure; and

    a layer or layer sequence reflective to the electromagnetic radiation applied to said radiation-diffusing structure.
