摘要:
An optoelectronic semiconductor chip has a first semiconductor functional region with a first terminal and a second terminal. A contact structure electrically contacts the optoelectronic semiconductor chip. The contact structure is connected electrically conductively to the first semiconductor functional region. The contact structure has a disconnectable conductor structure. An operating current path is established via the first terminal of the first semiconductor functional region and the second terminal if the conductor structure is not disconnected. This path is interrupted if the conductor structure is disconnected. Alternatively, an operating current path is established via the first terminal of the first semiconductor functional region and the second terminal if the conductor structure is disconnected. The conductor structure connects the first terminal to the second terminal and short circuits the first semiconductor functional region if the conductor structure is not disconnected.
