摘要： An optical semiconductor device with a multiple quantum well structure, is set out in which well layers and barrier layers, comprising various types of semiconductor layers, are alternately layered. The device well layers comprise a first composition based on a nitride semiconductor material with a first electron energy. The barrier layers comprise a second composition of a nitride semiconductor material with electron energy which is higher in comparison to the first electron energy. The well and barrier layers are in the direction of growth, by a radiation-active quatum well layer which with the essentially non-radiating well layers (6a) and the barrier layers (6b), arranged in front, form a supperlattice.

摘要： An illumination module with at least one thin-film light emitting diode chip which is applied on a chip carrier having electrical connecting conductors and has a first and a second electrical connection side and also an fabricated semiconductor layer sequence. The semiconductor layer sequence has an n-conducting semiconductor layer, a p-conducting semiconductor layer and an electromagnetic radiation generating region arranged between these two semiconductor layers and is arranged on a carrier. Moreover, it has a reflective layer at a main area facing toward the carrier, which reflective layer reflects at least one part of the electromagnetic radiation generated in the semiconductor layer sequence back into the latter. The semiconductor layer sequence has at least one semiconductor layer with at least one micropatterned, rough area. The coupling-out area of the thin-film light emitting diode chip is essentially defined by a main area remote from the reflective layer and is free of housing material such as potting or encapsulating material.
