The reduction of such impurities reduces the probability of incorporation of the impurities into the light emitting layer structure (155) which may affect the lifetime of the light emitting semiconductor device (100). The growth conditions are chosen out of the group consisting of arsenic partial pressure, oxygen partial pressure, deposition temperature, total deposition pressure and aluminum deposition rate. The invention further relates to a corresponding method of manufacturing such a light emitting semiconductor device (100).SELECTED DRAWING: Figure 1
