Optoelectronic semiconductor chip and method of producing an optoelectronic semiconductor chip
Abstract:
An optoelectronic semiconductor chip having a semiconductor layer sequence includes at least one active layer that generates primary radiation; a plurality of conversion layers that at least partially absorb the primary radiation and convert the primary radiation into secondary radiation of a longer wavelength than the primary radiation; and a roughened portion that extends at least into one of the conversion layers, wherein the roughened portion has a random structure, the semiconductor layer sequence is arranged on a carrier, a top side of the semiconductor layer sequence facing away from the carrier is formed by the roughened portion, the at least one active layer is located between the carrier and the conversion layers, and the roughened portion includes a plurality of recesses free of a semiconductor material.
