Abstract
A radiation-emitting semiconductor chip (1) comprising a thin-film semiconductor body (2) which has a semiconductor layer sequence with an active region (4) suitable for generating radiation, and a reflector layer (5) arranged on the thin-film semiconductor body. The semiconductor chip has a Bragg reflector in addition to the reflector layer, and the Bragg reflector (6) and the reflector layer are arranged on the same side of the active region.
