Abstract
An optoelectronic semiconductor chip, comprising a first contact location () and a second contact location (), and a reflective layer (), which is directly electrically conductively connected to the second contact location. The reflective layer contains a metal that tends toward migration, and the reflective layer is arranged in such a way that a migration path () for the metal can form between the second and the first contact location. A means () which, during operation of the semiconductor chip, forms an electric field that counteracts the migration of the metal is provided at the semiconductor chip.
