ABSTRACT:
A semiconductor chip, in particular a light-emitting diode, has a substrate (2), on which a sequence of semiconductor layers (3) with an active zone (5) has been applied. Above the sequence of semiconductor layers (3) there is a stepped window layer (6), which is structured in the manner of a Fresnel lens and has with regard to the coupling out of radiation the function of a hemispherical lens (7). This produces a semiconductor chip with particularly high coupling-out efficiency.
