  • OPTOELECTRONIC SEMICONDUCTOR BODIES HAVING A REFLECTIVE LAYER SYSTEM
    Publication number: 20120049228
    Abstract: An optoelectronic semiconductor body (1) having an active semiconductor layer sequence (10) and a reflective layer system (20) is described. The reflective layer system (20) comprises a first radiation-permeable layer (21), which adjoins the semiconductor layer sequence (10), and a metal layer (23) on the side of the first radiation-permeable layer (21) facing away from the semiconductor layer sequence (10). The first radiation-permeable layer (21) contains a first dielectric material. Between the first radiation-permeable layer (21) and the metal layer (23) there is disposed a second radiation-permeable layer (22) which contains an adhesion-improving material. The metal layer (23) is applied directly to the adhesion-improving material. The adhesion-improving material differs from the first dielectric material and is selected such that the adhesion of the metal layer (23) is improved in comparison with the adhesion on the first dielectric material.
