Title: METHOD FOR PRODUCING LIGHT-EMITTING DIODES, AND LIGHT-EMITTING DIODE
Abstract:
In one embodiment the method is designed for producing light-emitting diodes and comprises the following steps: A) providing a light-emitting diode chip (2) with a growth substrate (21) and a semiconductor layer sequence (22) for generating radiation, and providing a carrier (3) with carrier contact faces (32), B) soldering chip contact faces (23), which are disposed on a chip underside (26) of the semiconductor layer sequence (22) facing away from the growth substrate (21), to the carrier contact faces (32), C) applying a liquid connection means (4), which is permeable for the generated radiation, to a substrate upper side (20) of the growth substrate (21) facing away from the semiconductor layer sequence (22), and fastening a luminescent body (5) to the substrate upper side (20), wherein the connection means (4) is displaced partially from the substrate upper side (20) by the luminescent body (5), such that chip side faces (24) are covered primarily by the connection means (4), and D) generating a reflector (6) on outer faces (46), facing away from the light-emitting diode chip (2), of the connection means (4) on the chip side faces, wherein the outer faces (46) point in a direction away from the carrier (3).
