Light-emitting-diode chip comprising a sequence of GaN-based epitaxial layers which emit radiation and a method for producing the same

摘要

A light-emitting diode chip comprises a GaN-based, radiation-emitting epitaxial layer sequence, an active region, an n-doped layer and a p-doped layer. The p-doped layer is provided, on its main surface facing away from the active region, with a reflective contact metallization comprising a radioparent contact layer and a reflective layer. Methods for fabricating LED chips of this type by thin-film technology are provided, as are LED components containing such LED chips.
