Optoelectronic semiconductor chip and method for production thereof

A method for producing a plurality of optoelectronic semiconductor chips, the method comprising:

• providing a semiconductor layer sequence having a first semiconductor layer, an active region, and a second semiconductor layer;
• forming a trench structure that extends through the second semiconductor layer and the active region into the first semiconductor layer;
• forming a contact structure having a plurality of contact webs that are electrically conductively connected to the first semiconductor layer in the trench structure;
• attaching the semiconductor layer sequence on a carrier;
• singulating the carrier having the semiconductor layer sequence into the plurality of semiconductor chips;
• regionally forming a terminal layer directly to the second semiconductor layer;
• and
• forming a region of reduced conductivity in the second semiconductor layer.

An optoelectronic semiconductor chip comprising:

• a carrier;
• and
• a semiconductor body arranged on the carrier,
• wherein the semiconductor body has a semiconductor layer sequence having an active region provided for generating or receiving radiation, a first semiconductor layer, and a second semiconductor layer,
• wherein the active region is arranged between the first semiconductor layer and the second semiconductor layer,
• wherein the first semiconductor layer is arranged on a side of the active region facing away from the carrier,
• wherein a trench structure is formed in the semiconductor body, the trench structure extending through the second semiconductor layer and the active region into the first semiconductor layer,
• wherein an electrical contact structure having a plurality of contact webs is disposed between the carrier and the semiconductor body,
• wherein the contact webs are electrically conductively connected to the first semiconductor layer in the trench structure,
• wherein the second semiconductor layer directly adjoins the contact structure, and
• wherein the second semiconductor layer includes a region that has a reduced conductivity in comparison to remaining portions of the second semiconductor layer.
