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

A semiconductor component comprising:

• an electrical contact arranged on a semiconductor layer,
• wherein the contact comprises a plurality of contact rods,
• wherein intermediate spaces between the contact rods are filled with a filler material,
• wherein the contact rods are electrically conductively connected to one another on a side facing away from the semiconductor layer via a contact layer, and
• wherein the contact rods have a density of at least 1,000,000 pieces per mm2 at least in places.

A method for producing an electrical contact on a semiconductor layer, the method comprising:

• providing the 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, wherein the second material grows between the first material and the semiconductor layer, 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.
