Abstract
A radiation-emitting semiconductor component has a semiconductor body containing a nitride compound semiconductor, and a contact metallization layer disposed on a surface of the semiconductor body. In this case, the contact metallization layer is covered with a radiation-transmissive, electrically conductive contact layer. The radiation generated is coupled out through the contact metallization layer or through openings in the contact metallization layer.
