Patent ID: 10181494

Abstract:
The invention relates to a method for producing an optoelectronic semiconductor chip (1). A semiconductor layer sequence (3) is provided, comprising a first semiconductor layer (3a) and a second semiconductor layer (3b). Furthermore, a first contact layer (5a) is provided which extends laterally along the first semiconductor layer (3a) and electrically contacts same. A third semiconductor layer (7) is applied onto a first contact layer (5a) face facing away from the semiconductor layer sequence (3). A recess (8) is formed which extends through the third semiconductor layer (7), the first contact layer (5a), and the first semiconductor layer (3a) into the second semiconductor layer (3b). A passivation layer (9) is applied onto a third semiconductor layer (7) face facing away from the semiconductor layer sequence (3). At least one first (9a) and at least one second passage opening (9b, 9c) are formed in the passivation layer (9). A second contact layer (5b) is applied which electrically contacts the second semiconductor layer (3b) in the region of the at least one first passage opening (9a) and the third semiconductor layer (7) in the region of the at least one second passage opening (9b, 9c). The invention additionally relates to an optoelectronic semiconductor chip (1).
