Patent ID: 7227191

Claim:
An optoelectronic component having a semiconductor chip containing a semiconductor layer sequence ( 6 ) with a radiation-emitting active zone ( 4 ), the semiconductor layer sequence ( 6 ) having sidewalls ( 10 ), and a connection contact ( 9 ) for impressing current into the active zone ( 4 ), wherein a first current expansion layer ( 7 ) adjoining a semiconductor layer ( 5 ) of the semiconductor layer sequence ( 6 ) and a second current expansion layer ( 8 ) are arranged between the semiconductor layer sequence ( 6 ) and the connection contact ( 9 ), the first current expansion layer ( 7 ) having a larger sheet resistance than the second current expansion layer ( 8 ) and forming an ohmic contact with the adjoining semiconductor layer ( 5 ), and the second current expansion layer ( 8 ) being applied to a partial region of the first current expansion layer ( 7 ) which is at a distance from the sidewalls ( 10 ).
