  • Patent number: 8138511
    Abstract: A radiation-emitting semiconductor component has an improved radiation efficiency. The semiconductor component has a multilayer structure with an active layer for generating radiation within the multilayer structure and also a window having a first and a second main surface. The multi-layer structure adjoins the first main surface of the window.

  • Patent number: 7592636
    Abstract: A radiation-emitting semiconductor component having a radiation-transmissive substrate (1), on the underside of which a radiation-generating layer (2) is arranged, in which the substrate (1) has inclined side areas (3), in which the refractive index of the substrate (1) is greater than the refractive index of the radiation-generating layer, in which the difference in refractive index results in an unilluminated substrate region (4), into which no photons are coupled directly from the radiation-generating layer, and in which the substrate (1) has essentially perpendicular side areas (5) in the unilluminated region. The component has the advantage that it can be produced with a better area yield from a wafer.
