Abstract

An optoelectronic component may have a semiconductor chip designed to emit electromagnetic radiation. The semiconductor chip may have a radiation exit surface, and a protective layer arranged over the radiation exit surface. The protective layer may include at least one first layer comprising an aluminum oxide and at least one second layer comprising a silicon oxide a silicon oxide, and at least one third layer comprising a titanium oxide. A current spreading layer may include one or more transparent conductive oxides arranged between the radiation exit surface and the protective layer.
