Patent ID: 11935989
Assignee: OSRAM OPTO SEMICONDUCTORS GMBH
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A method for producing an optoelectronic semiconductor chip, wherein the method comprises:
providing a first region on a second region, wherein the first region is doped with a first dopant and the second region is doped with a second dopant and an active region is arranged between the first region and the second region,
applying a first contact layer on the first region, wherein the first contact layer comprises an electrically conductive material,
applying an insulating layer,
etching first openings in the insulating layer, wherein the first openings completely penetrate the insulating layer,
applying a second contact layer on the insulating layer and the first openings,
wherein the second contact layer comprises an electrically conductive material, and
etching second openings in the second contact layer and/or applying a third contact layer in the first openings before applying the second contact layer, wherein the third contact layer comprises an electrically conductive material;
wherein the second contact layer is in direct contact with the insulating layer and wherein one first opening is arranged in a lateral direction between two second openings, respectively.
