  • Optoelectronic semiconductor device and method for producing an optoelectronic semiconductor device
    Patent number: 11127880
    Abstract: An optoelectronic semiconductor device and a method for producing an optoelectronic semiconductor device are disclosed. In an embodiment an optoelectronic semiconductor device includes a semiconductor body having a first region of a first conductivity type, an active region configured to generate electromagnetic radiation and a second region of a second conductivity type in a stacking direction, an electrical contact metallization arranged on a side of the second region facing away from the active region and being opaque to the electromagnetic radiation, a radiation coupling-out region surrounding the electrical contact metallization at an edge side and an absorber layer structure arranged between the electrical contact metallization and the second region.
    Type: Grant
