Abstract
An optoelectronic semiconductor chip may include a semiconductor layer sequence provided for generating and/or receiving radiation. The chip may further include a first trench structure and a second trench structure formed in the semiconductor layer sequence. A first contact finger structure may electrically conductively connect the second trench structure to a first semiconductor layer of the semiconductor layer sequence. The first contact finger structure may adjoin a first side surface and/or a second side surface of the second trench structure at least in places. A second contact finger structure may electrically conductively connect to a second semiconductor layer of the semiconductor layer sequence where the second contact finger may be arranged in the first trench structure.
