    摘要: An LED chip includes a carrier, a semiconductor layer sequence, a reflective layer sequence arranged in regions between the carrier and the semiconductor layer sequence, wherein the reflective layer sequence includes a dielectric layer facing the semiconductor layer sequence and a metallic mirror layer facing away from the semiconductor layer sequence, and an encapsulating layer arranged in places between the carrier and the reflective layer sequence, the encapsulating layer extending in places through the reflective layer sequence into the semiconductor layer sequence and thus forming a separating web separating an inner region of the reflective layer sequence from an edge region of the reflective layer sequence.

    摘要: The invention relates to a semiconductor component with a semiconductor chip and a radiation conversion element which is arranged on the semiconductor chip. The semiconductor chip has an active region which is designed to generate a primary radiation with a peak wavelength, the radiation conversion element has a quantum structure, the peak wavelength of the primary radiation lies in the infrared spectral range, and the quantum structure at least partly converts the primary radiation into a secondary radiation, wherein the emission wavelength of an emission maximum of the secondary radiation is greater than the peak wavelength. The invention additionally relates to a method for producing radiation conversion elements.
