Abstract:
1. A radiation-emitting semiconductor chip, comprising: a semiconductor layer sequence having at least one active layer that generates electromagnetic radiation; a single continuous electrical contact layer arranged on the at least one active layer, said single continuous electrical contact layer comprising a connection region and a current injection region which is arranged at a distance beside the connection region and electrically connected thereto; and an absorbent brightness setting layer between the connection region and the current injection region and/or, as seen from the connection region, outside the current injection region on a front-side radiation coupling-out area of the semiconductor layer sequence, said brightness setting layer absorbing in a targeted manner part of the radiation generated in the semiconductor layer sequence; wherein the absorbent brightness setting layer includes a metal or an alloy comprised of at least two metals, and wherein the absorbent brightness setting layer extends beyond the connection region of the single continuous electrical contact layer in a lateral direction.
