Assignee: OSRAM OPTO SEMICONDUCTORS GMBH
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. An optoelectronic semiconductor chip with:
a first region doped with a first dopant,
a second region doped with a second dopant,
an active region between the first region and the second region,
a first contact layer comprising an electrically conductive material and covering the first region,
an insulating layer covering the first contact layer and comprising first openings, and
a second contact layer comprising an electrically conductive material and covering the insulating layer and the first openings, wherein:
the first openings completely penetrate the insulating layer,
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;
the first contact layer comprises a transparent conductive oxide; and
the second contact layer is in direct contact with the insulating layer.
