摘要:
A method of manufacturing an optoelectronic component includes: A) providing a substrate, B) providing a metallic liquid arranged in a structured manner and in direct mechanical contact on the substrate and including at least one first metal, C) providing semiconductor chips each having a metallic termination layer on their rear side, the metallic termination layer including at least one second metal different from the first metal, and D) self-organized arranging the semiconductor chips on the metallic liquid so that the first metal and the second metal form at least one intermetallic compound having a higher re-melting temperature than the melting temperature of the metallic liquid, wherein the intermetallic compound is a connecting layer between the substrate and the semiconductor chips.
