Abstract
An optoelectronic semiconductor chip, comprising a plurality of semiconductor function regions (10) arranged on a common carrier layer (1, 7), at least one of the semiconductor function regions being a defect region (12), and a contact structure (18) for making electrical contact with the optoelectronic semiconductor chip. The contact structure is electrically conductively connected to at least one of the semiconductor function regions, and the contact structure is adapted to be electrically separated, or it is electrically separated, from the defect region.
