Claim:
1. An optoelectronic semiconductor chip comprising: a semiconductor body of semiconductor material comprising a p-side, an n-side and an active layer between the p-side and the n-side, the active layer configured to generate radiation during operation; a p-contact layer electrically contacting the p-side of the semiconductor body; and an n-contact layer electrical contacting the n-side of the semiconductor body, wherein the n-contact layer contains a transparent conductive oxide (TCO) layer and a mirror layer, the TCO layer being arranged between the n-side of the semiconductor body and the mirror layer, wherein the n-contact layer passes through the p-side of the semiconductor body via a hole, wherein the hole projects into the n-side of the semiconductor body, and wherein the TCO layer is arranged in the hole between the n-side of the semiconductor body and the mirror layer.
