Abstract

According to the invention, a semiconductor component for the emission of electromagnetic radiation, especially light, is made that has the following features: an active layer for producing radiation, a p-type contact that is electrically connected to the active layer, an n-type contact that is electrically connected to the active layer, and a current-confining structure to define a current path, with the current-confining structure being provided between the n-type contact and the active layer.
