| 摘要 |
The invention relates to a semiconductor chip, especially a light-emitting diode, having a substrate (2) on which a semiconductor layer sequence (3) with an active zone (5) is applied. A graded, Fresnel lens-like structured window layer (6) is located above the semiconductor layer sequence (3), which functions as a semicircular lens (7) with regard to radiation decoupling, resulting in a semiconductor chip with a particularly high decoupling efficiency. |
