METHOD FOR PRODUCING AN ELECTROMAGNETIC RADIATION-EMITTING SEMICONDUCTOR CHIP AND A CORRESPONDING ELECTROMAGNETIC RADIATION-EMITTING SEMICONDUCTOR CHIP

摘要

The invention relates to a method for producing a radiation-emitting semiconductor chip based on AlGaInP, comprising the following steps: preparing a substrate; applying a series of semiconductor layers to the substrate, said series of layers containing a photon-emitting active layer, and; applying a transparent decoupling layer comprising Gax(InyAl1-y)1-xP, whereby 0.8 <= x and 0 <= y <= 1. The invention provides that the substrate is made from germanium and that the transparent decoupling layer is applied at a low temperature.
