Abstract (en)
[origin: WO2010022694A1] A semiconductor chip is specified, comprising an active layer (2) provided for emitting an electromagnetic radiation, and a two-dimensional arrangement of structure units (5), which is disposed downstream of the active layer in a main emission direction (6) of the semiconductor chip. The structure units (5) are arranged in an arbitrary statistical distribution. A semiconductor chip having a directional emission characteristic can be realized by means of such an arrangement of structure units.
