Claim:
1. A nitride semiconductor component comprising a layer structure having a first gallium nitride layer and an aluminum-containing nitride intermediate layer, wherein the aluminum-containing nitride intermediate layer adjoins the first gallium nitride layer, the layer structure has an undoped second gallium nitride layer adjoining the aluminum-containing nitride intermediate layer, the layer structure has a third gallium nitride layer, the third gallium nitride layer has a silicon doping which is variable perpendicular to the layer plane, the third gallium nitride layer adjoins the second gallium nitride layer, doping of the third gallium nitride layer increases proceeding from an interface with the second gallium nitride layer, the layer structure has a fourth gallium nitride layer, the fourth gallium nitride layer has a silicon doping, the fourth gallium nitride layer adjoins the third gallium nitride layer, the layer structure comprises an LED layer structure adjoining the fourth gallium nitride layer, and a proportion of aluminum increases throughout the aluminum-containing nitride intermediate layer in a direction of the undoped second gallium nitride layer.
