Patent ID: 10950746

Abstract:
A method for producing a plurality of optoelectronic components are disclosed. In an embodiment, the method includes providing a substrate, epitaxially applying a sacrificial layer on the substrate, wherein the sacrificial layer has a layer thickness greater than 300 nm and comprises AlxGa(1-x)As with 0<x≤1, epitaxially applying a semiconductor layer sequence on the sacrificial layer, forming trenches extending in a vertical direction through the semiconductor layer sequence to the sacrificial layer such that a plurality of regions in the semiconductor layer sequence is formed and wet thermally oxidizing the sacrificial layer such that the substrate is non-destructively removable from the semiconductor layer sequence, wherein the sacrificial layer comprises at least three and optionally four sublayers in a direction facing away from the substrate, a first sublayer comprising InGaAlP, a second sublayer comprising GaAs, a third sublayer comprising AlxGa(1-x)As with 0<x≤1 and a fourth sublayer comprising GaAs.
