Patent ID: 8592840

Claim:
An optoelectronic semiconductor chip comprising: an epitaxially grown semiconductor layer sequence based on GaN, InGaN, AlGaN and/or InAlGaN, a p-doped layer sequence, an n-doped layer sequence, an active zone that generates an electromagnetic radiation, is situated between the p-doped layer sequence and the n-doped layer sequence, and is penetrated by an electrical plated-through hole, and at least one Al x Ga 1-x N-based intermediate layer where 0≦x≦1, which is situated at a same side of the active zone as the n-doped layer sequence, wherein at least one of a) or b) is present: a) the intermediate layer has elevations extending into cracks and/or holes in a layer of the semiconductor layer sequence that adjoins the intermediate layer, wherein the elevations at least in places are in direct contact with boundary areas of the cracks and/or holes and at least some or all of the cracks and/or holes are completely covered by the intermediate layer, b) the intermediate layer reduces a size of the cracks and/or holes along a growth direction of the semiconductor layer sequence, wherein at least one portion of the cracks and/or holes extends on both sides of the intermediate layer.
