  • Publication number: 20170324000
    Abstract: An optoelectronic semiconductor chip has a semiconductor body and a substrate on which the semiconductor body is disposed. The semiconductor body has an active region disposed between a first semiconductor layer of a first conductor type and a second semiconductor layer of a second conductor type. The first semiconductor layer is disposed on the side of the active region facing the substrate. The first semiconductor layer is electrically conductively connected to a first termination layer that is disposed between the substrate and the semiconductor body. An encapsulation layer is disposed between the first termination layer and the substrate and, in plan view of the semiconductor chip, projects at least in some regions over a side face which delimits the semiconductor body.

  • Patent number: 8710512
    Abstract: An optoelectronic semiconductor chip, comprising a first contact location (1) and a second contact location (2), and a reflective layer (3), 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 (4) for the metal can form between the second and the first contact location. A means (6) which, during operation of the semiconductor chip, forms an electric field that counteracts the migration of the metal is provided at the semiconductor chip.
