Abstract

The invention relates to a method for producing a semiconductor component comprising a radiation-emitting optical semiconductor chip or a plurality of radiation-emitting optical semiconductor chips, said method comprising: applying the radiation-emitting optical semiconductor chip or the plurality of radiation-emitting optical semiconductor chips to a deformable flat support deforming the support; and permanently fixing the deformation.

Claims (38)

1. A method for producing a semiconductor component comprising one radiation-emitting optical semiconductor chip or a plurality of radiation-emitting optical semiconductor chips, comprising:

applying the radiation-emitting optical semiconductor chip or the plurality of radiation-emitting optical semiconductor chips on a deformable flat carrier, wherein the deformable flat carrier has a plurality of plated through holes,

deforming the carrier and permanently fixing the deformation, wherein the carrier is deformed by bending or curving by way of a shaping part and the bent or curved carrier is casted in order to fix the deformation,

wherein the shaping part is removed after casting and the resultant cavity is filled or the shaping part remains in the deformed carrier after casting, and

wherein the radiation-emitting optical semiconductor chip or the plurality of radiation-emitting optical semiconductor chips is/are arranged in an angular fashion with respect to a base side of the semiconductor component.

2. The method as claimed in claim 1 ,

comprising introducing cutouts into the carrier.

3. The method as claimed in claim 1 ,

wherein a thermoplastic deformation of the carrier is effected, which maintains its deformation after cooling.

4. The method as claimed in claim 1 ,

wherein the deformation of the carrier is effected by thermoforming by means of compressed air and/or vacuum or by means of a press.

5. The method as claimed in claim 4 ,

wherein the deformed carrier is encapsulated with a plastics layer.

6. The method as claimed in claim 1 ,

wherein the semiconductor chip or the plurality of semiconductor chips is/are enclosed by molding on the carrier.

7. The method as claimed in claim 1 ,

wherein the carrier with the semiconductor chips is singulated to form semiconductor components after the deformation has been fixed.

8. A semiconductor component comprising one radiation-emitting optical semiconductor chip or a plurality of radiation-emitting optical semiconductor chips on a carrier having flexible conductor tracks, which carrier has been permanently deformed after the process of applying the radiation-emitting optical semiconductor chip or the plurality of radiation-emitting optical semiconductor chips, such that the radiation-emitting optical semiconductor chip or the plurality of radiation-emitting optical semiconductor chips is/are arranged in an angular fashion with respect to a base side of the semiconductor component, wherein the carrier has a plurality of plated through holes.

9. The semiconductor component as claimed in claim 8 ,

wherein the carrier comprises a thermoplastically deformed material.

10. The semiconductor component as claimed in claim 8 ,

wherein the carrier has a region which rises above the base side or is recessed from the latter and on which the radiation-emitting optical semiconductor chip or at least one portion of the plurality of radiation-emitting optical semiconductor chips is arranged.

11. The semiconductor component as claimed in claim 10 ,

wherein the region which rises above the base side or is recessed from the latter is arranged on a shaping part.

12. The semiconductor component as claimed in claim 10 ,

wherein the region which rises above the base side or is recessed from the latter is a domed region or has a wedge-shaped or truncated-wedge-shaped cross section.

13. The semiconductor component as claimed in claim 10 ,

wherein the plurality of radiation-emitting optical semiconductor chips are arranged on opposite sides of the region which rises above the base side or is recessed from the latter.

14. The semiconductor component as claimed in claim 8 ,

wherein the carrier has cutouts.

15. The semiconductor component as claimed in claim 8 ,

wherein a first semiconductor chip from the plurality of radiation-emitting optical semiconductor chips is at a first distance from the base side, which first distance is smaller than a second distance between a second semiconductor chip from the plurality of radiation-emitting optical semiconductor chips and the base side.

16. The semiconductor component as claimed in claim 8 ,

wherein a casting on a carrier top side encloses the radiation-emitting optical semiconductor chip or the plurality of radiation-emitting optical semiconductor chips.

17. The semiconductor component as claimed in claim 16 ,

wherein the casting comprises a first material layer, in which there is an active region of a semiconductor chip from the plurality of radiation-emitting optical semiconductor chips, and a second material layer, in which there is an active region of a further semiconductor chip from the plurality of radiation-emitting optical semiconductor chips.

18. The semiconductor component as claimed in claim 8 ,

wherein one or more heat-dissipating regions are arranged in the carrier below the radiation-emitting optical semiconductor chip or the plurality of radiation-emitting optical semiconductor chips.
