Methods for producing optoelectronic semiconductor components, and optoelectronic semiconductor lasers
Abstract:
A method for producing an optoelectronic semiconductor component includes: epitaxially growing a semiconductor layer sequence including an active layer on a growth substrate, shaping a front facet at the semiconductor layer sequence and the growth substrate, coating a part of the front facet with a light blocking layer for radiation generated in the finished semiconductor component, wherein the light blocking layer is produced by a directional coating method and the light blocking layer is structured during coating by shading by the growth substrate and/or by at least one dummy bar arranged at and/or alongside the growth substrate.
