摘要:
An optoelectronic semiconductor chip includes a semiconductor layer stack and a mirror. The semiconductor layer stack has an active layer for generating electromagnetic radiation. The minor is arranged on an underside of the semiconductor layer stack. The mirror has a first region and a second region, the first region containing silver and the second region containing gold. A method of producing such a semiconductor chip is also defined.
