Abstract:
Provided is an optoelectronic semiconductor chip including a semiconductor layer sequence in which an active zone for generating radiation is located between a first semiconductor region and a second semiconductor region. A first electrical contact of the semiconductor layer sequence is applied to the first semiconductor region. A second electrical contact is applied to the second semiconductor region. The second electrical contact is located in a trench of the second semiconductor region. The trench is restricted to the second semiconductor region and ends at a distance from the active zone. A distance between a bottom of the trench and the active zone is at most 3 μm.
