Abstract
An optoelectronic semiconductor device may include a semiconductor layer sequence, a directionally reflective layer being arranged on the first main surface of the semiconductor layer sequence, a first contact structure comprising a first current spreading structure arranged on a first surface of a first semiconductor layer of the semiconductor layer sequence, a second contact structure comprising a second current spreading structure arranged on a first surface of a second semiconductor layer of the layer stack, wherein the first current spreading structure and the second current spreading structure each consist of at least one transparent conductive oxide. Moreover, a method for producing an optoelectronic semiconductor device is described.
