Abstract

In an embodiment, a method for producing a plurality of optoelectronic semiconductor components is disclosed, wherein the method includes inserting a plurality of optoelectronic semiconductor chips with a suitable orientation into a linear feeding device, conveying the optoelectronic semiconductor chips to an injection device having an outlet opening, encapsulating the optoelectronic semiconductor chips with at least one cladding layer in the injection device and pressing the encapsulated optoelectronic semiconductor chips out of the outlet opening, wherein a compound of optoelectronic semiconductor chips is formed in which the optoelectronic semiconductor chips are connected to one another by the at least one cladding layer and separating the compound into a plurality of optoelectronic semiconductor components each component having an optoelectronic semiconductor chip which is at least partially encapsulated by the at least one cladding layer.

Claims (15)

1. A method for producing a plurality of optoelectronic semiconductor components and/or at least one optoelectronic module, the method comprising:

inserting a plurality of optoelectronic semiconductor chips with a suitable orientation into a linear feeding device;

conveying the optoelectronic semiconductor chips to an injection device having an outlet opening;

encapsulating the optoelectronic semiconductor chips with at least one cladding layer in the injection device and pressing the encapsulated optoelectronic semiconductor chips out of the outlet opening, wherein a compound of optoelectronic semiconductor chips is formed in which the optoelectronic semiconductor chips are connected to one another by the at least one cladding layer; and

separating the compound into a plurality of optoelectronic semiconductor components each component having an optoelectronic semiconductor chip which is at least partially encapsulated by the at least one cladding layer, and/or separating the compound into at least one optoelectronic module comprising a plurality of optoelectronic semiconductor chips which are at least partially encapsulated and connected to one another by the at least one cladding layer.

2. The method according to claim 1 , wherein a shape of the outlet opening determines the shape of the optoelectronic semiconductor components or the optoelectronic module such that a cross-section of the outlet opening corresponds to a cross-section of the optoelectronic semiconductor components or the optoelectronic module.

3. The method according to claim 1 , wherein the outlet opening has a polygonal cross-section, and wherein a prismatic bond is formed when pressed out.

4. The method according to claim 1 , wherein the outlet opening has an oval cross-section, and wherein a cylindrical compound is produced when pressed out.

5. The method according to claim 1 , wherein the optoelectronic semiconductor chips are introduced one after the other into the feeding device.

6. The method according to claim 1 , wherein a material used for the cladding layer is supplied transversely to a conveying direction of the optoelectronic semiconductor chips.

7. The method according to claim 1 , wherein the injection device has a plurality of injection regions from which different materials are supplied.

8. The method according to claim 7 , wherein different cladding layers are produced from the different materials.

9. The method according to claim 7 , wherein the injection regions are arranged one after the other in a conveying direction of the optoelectronic semiconductor chips and various cladding layers are produced by the injection regions, wherein the cladding layers are arranged one after the other in a direction running transversely to the conveying direction starting from the optoelectronic semiconductor chips.

10. The method according to claim 1 , wherein at least one of the following materials is used for the at least one cladding layer: a thermoplastic resin or an epoxy resin or silicone.

11. The method according to claim 1 , wherein the optoelectronic semiconductor chips are introduced into the feeding device in a compound manner, the optoelectronic semiconductor chips being connected to one another by a mount and/or a connection means.
