Method for producing an electromagnetic radiation-emitting semiconductor chip and a corresponding electromagnetic radiation-emitting semiconductor chip

摘要

In a method of fabricating a radiation-emitting semiconductor chip based on AlGaInP, comprising the method steps of preparing a substrate, applying to the substrate a semiconductor layer sequence comprising a photon-emitting active layer, and applying a transparent decoupling layer comprising(Ga_x(In_yAl_1-y)_1-xP wherein 0.8<=x and 0<=y<=1, it is provided according to the invention that the substrate is made of germanium and that the transparent decoupling layer is applied at low temperature.
