A method for producing an electrical contact on a semiconductor layer and a semiconductor component having an electrical contact are disclosed. In an embodiment a method includes providing a semiconductor layer, forming a plurality of contact rods on the semiconductor layer, wherein the contact rods are formed by a first material and a second material, wherein the first material is applied to the semiconductor layer and the second material is applied to the first material, and wherein a lateral structure of the first material is self-organized, forming a filling layer on the contact rods and in intermediate spaces between the contact rods and exposing the contact rods.

Method for establishing electrical contact of a semiconductor layer and semiconductor component having electrical contact

A semiconductor chip, an optoelectronic device including a semiconductor chip, and a method for producing a semiconductor chip are disclosed. In an embodiment the chip includes a semiconductor body with a first main surface and a second main surface arranged opposite to the first main surface, wherein the semiconductor body includes a p-doped sub-region, which forms part of the first main surface, and an n-doped sub-region, which forms part of the second main surface and a metallic contact element that extends from the first main surface to the second main surface and that is electrically isolated from one of the sub-regions.
