Abstract

A light-emitting semiconductor component having: a semiconductor element containing an active layer, electrical contacts for impressing a current into the active layer (heat being generated at the active layer and at the electrical contacts during operation), and a carrier with a large thermal capacity for absorbing the heat generated during operation. The rear side of the semiconductor element is electrically and thermally connected to the carrier by a conductive adhesive. Recesses, which accommodate a part of the conductive adhesive when the semiconductor element is connected to the carrier, are provided in the rear side of the semiconductor element.
