摘要： A light-emitting semiconductor component includes a thin film stack having a front side and a rear side, a photon-emitting zone formed in an active layer, and contact points formed on the front side and rear side of the thin film stack to impress current into the active layer. The photon-emitting zone is separated physically from the contact points in the plane of the thin film stack. As a result, the absorption of the radiation at the contact points can be minimized.
