OPTOELECTRONIC SEMICONDUCTOR CHIP, AND METHOD FOR THE FABRICATION THEREOF

摘要

An optoelectronic semiconductor chip (10) is provided which has a semiconductor layer stack (3) and a mirror (2). The semiconductor layer stack (3) has an active layer (3a) for producing electromagnetic radiation. The mirror (2) is arranged on an underside of the semiconductor layer stack (3). The mirror (2) has a first region (2a) and a second region (2b), wherein the first region (2a) contains silver and the second region (2b) contains gold. In addition, a method for fabricating such a semiconductor chip (10) is specified.
