Abstract:
1. An optoelectronic semiconductor chip comprising: an active layer with a first and a second major face, comprising a semiconductor material which emits or receives radiation when the semiconductor chip is in operation; a patterned layer comprising three-dimensional patterns for outcoupling or incoupling radiation and arranged on the first major face in a beam path of the radiation; wherein the patterned layer comprises an inorganic-organic hybrid material comprising 1) a hydrolytic condensation product containing organofunctional silanes with organic substituents which are at least in part crosslinked with the organic prepolymer, and 2) an organic prepolymer and the inorganic-organic hybrid material contain at least 20 wt. % of titanium and/or zirconium that is chemically bonded to the inorganic-organic hybrid material.
