Abstract

A method of producing optoelectronic components includes providing an auxiliary carrier, forming separate connection elements on the auxiliary carrier, forming a molded body on the auxiliary carrier with recesses, arranging optoelectronic semiconductor chips on connection elements in the recesses of the molded body, removing the auxiliary carrier, and severing the molded body to form singulated optoelectronic components.

Claims (20)

1. A method of producing optoelectronic components comprising:

providing an auxiliary carrier;

forming separate connection elements on the auxiliary carrier;

forming a molded body on the auxiliary carrier with recesses;

arranging optoelectronic semiconductor chips on connection elements in the recesses of the molded body;

removing the auxiliary carrier; and

severing the molded body to form singulated optoelectronic components,

wherein the molded body is formed on the auxiliary carrier, the molded body covers a part of the auxiliary carrier such that the auxiliary carrier is exposed in separate opening regions, after forming the molded body the separate connection elements are formed, and forming the separate connection elements comprises applying material on the auxiliary carrier in the opening regions.

2. The method according to claim 1 , wherein forming the separate connection elements comprises applying material on the auxiliary carrier in separate application regions.

3. The method according to claim 1 , wherein forming the separate connection elements comprises carrying out one of electrochemical deposition, sputtering process or chemical deposition.

4. The method according to claim 1 , wherein forming the separate connection elements comprises carrying out a printing process.

5. The method according to claim 1 , wherein the molded body is a masking layer for forming the separate connection elements in the opening regions.

6. The method according to claim 1 , wherein forming the separate connection elements comprises carrying out one of electrochemical deposition or chemical deposition.

7. The method according to claim 1 , further comprising introducing a potting compound into the recesses of the molded body.

8. The method according to claim 1 , wherein the auxiliary carrier comprises an electrically conductive material.

9. The method according to claim 1 , wherein the auxiliary carrier comprises a first layer and a second layer, and the connection elements and the molded body are formed on the second layer.

10. The method according to claim 1 , wherein removing the auxiliary carrier is carried out by an etching process.

11. The method according to claim 1 , wherein removing the auxiliary carrier is carried out by a laser lift-off process.

12. The method according to claim 11 , wherein the auxiliary carrier comprises a first layer composed of glass and a second layer composed of a different material, the connection elements and the molded body are formed on the second layer, and in the laser lift-off process radiation of a laser is transmitted through the first layer to decompose the second layer.

13. An optoelectronic component produced by carrying out the method according to claim 1 , wherein the component comprises a housing body produced by severing of the molded body, and the component comprises a circumferential lateral surface formed exclusively by the housing body.
