Patent ID: 8710486

Claim:
An optoelectronic semiconductor chip comprising: a semiconductor body having a semiconductor layer sequence with an active region suitable for generating radiation; a radiation-transmissive and electrically conductive contact layer arranged on the semiconductor body and electrically connected to the active region, the contact layer directly adjoining both a barrier layer of the semiconductor layer sequence and a connection layer applied to the semiconductor body and having a structure; and an electrode arranged on the semiconductor body on a side of the active region facing away from the barrier layer, the electrode having a connection area, wherein the connection layer has a cut out in a region of the barrier layer, wherein the region of the barrier layer where the connection layer has a cut out is free of the connection layer, wherein the contact layer directly adjoins the barrier layer in the region of the barrier layer, wherein from a top view of the active region of the semiconductor layer sequence, the region of the barrier layer covers the entire electrode, wherein the connection layer and the contact layer both adjoin the barrier layer, wherein the connection layer and the contact layer both comprise a radiation-transmissive and electrically conductive oxide, and wherein the connection layer and the contact layer are doped differently or their materials are selected such that an electrical contact resistance of the contact layer to the connection layer is lower than an electrical contact resistance of the contact layer to the barrier layer.
