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.

Claims (9)

1. A semiconductor component which performs at least one of a radiation-emitting function and a radiation-receiving function, comprising:

a lead frame having a chip carrier part and a connection part;

a semiconductor chip which performs at least one of a radiation-emitting and radiation-receiving function and which is secured on the chip carrier part;

an encapsulation surrounding the semiconductor chip and at least a partial region of the chip carrier part;

said connection part being arranged at a distance from the chip carrier part;

said chip carrier part and said connection part each having two external connections which project from the encapsulation at opposite sides.

2. A semiconductor component as claimed in claim 1 , wherein said encapsulation further comprises a base body having formed a recess therein and a radiation-permeable window arranged in the recess and wherein the semiconductor chip is positioned within the recess.

3. A semiconductor component as claimed in claim 2 , wherein the recess having inner surfaces which are coated with reflection-enhancing material.

4. A semiconductor component as claimed in claim 1 , wherein the encapsulation is formed completely of a radiation-permeable material.
