Latest Patents

Among her latest innovations are two notable patents related to optoelectronic semiconductor chips. The first patent describes an optoelectronic semiconductor chip that includes a semiconductor layer sequence with an active zone for generating radiation. This semiconductor layer sequence is based on AlInGaP and/or AlInGaAs. A metal mirror for the radiation is positioned on the rear side of the semiconductor layer sequence, opposite the light extraction side. The design incorporates a protective metallization applied directly to the side of the metal mirror that faces away from the semiconductor layer sequence. Additionally, an adhesion-promoting layer is situated directly on the side of the metal mirror facing the semiconductor layer sequence, encapsulating the metal mirror at least at one outer edge.

The second patent also focuses on an optoelectronic semiconductor chip, which includes a semiconductor layer sequence featuring an active layer, a doped current spreading layer, and an output coupling layer arranged in a specific order. The active layer generates primary radiation during operation, while the current spreading layer exhibits greater lateral electrical conductivity than the output coupling layer. The output coupling layer is designed with structures for coupling out radiation on an exit side that faces away from the active layer, and it has a lower absorption coefficient for primary radiation compared to the current spreading layer.
