Abstract
An optoelectronic semiconductor chip may include a first region doped with a first dopant, a second region doped with a second dopant, an active region between the first and second regions, a first contact layer having an electrically conductive material and covering the first region. An insulating layer may cover the first contact layer and include first openings, and the insulating layer may include a second contact layer having an electrically conductive material and covering the insulating layer and the first openings. The first openings may completely penetrate the insulating layer, and the second contact layer may include second openings and/or a third contact layer comprising an electrically conductive material is arranged in the first openings in each case between the second contact layer and the insulating layer.
