ABSTRACT:
A radiation-emitting and/or radiation-receiving semiconductor component in which a radiation-emitting and/or radiation-receiving semiconductor chip is secured on a chip carrier part of a lead frame. The chip carrier part forms a trough in the region in which the semiconductor chip is secured wherein the inner surface of the trough is designed in such a way that it constitutes a reflector for the radiation emitted and/or received by the semiconductor chip.
