Abstract

The invention relates to an optoelectronic semiconductor chip (10) comprising a carrier (2) and a semiconductor body (1) having an active layer (13) provided for generating electromagnetic radiation. Said carrier (2) has a first main surface (2A) facing the semiconductor body, a second main surface (2B) facing away from the semiconductor body, and a sidewall (2C) arranged between the first main surface and the second main surface. The carrier (2) has a structured region (21, 22, 23, 2C) for enlarging the total surface area of the sidewall, wherein the structured region has singulation traces. The invention also relates to an optoelectronic component (100) comprising such a semiconductor chip and a method for producing a plurality of such semiconductor chips are specified.
