Claim Text:
1. A method for producing an optoelectronic component, comprising: providing a semiconductor layer sequence having at least one active region, wherein the at least one active region emits electromagnetic radiation during operation; and applying, with an ion assisted application method, at least one layer directly on a first surface of the semiconductor layer sequence such that the at least one layer has a peak-to-peak roughness of less than approximately 4 nm, applying, with an ion assisted application method, at least one layer directly on a second surface of the semiconductor layer sequence such that the at least one layer has a peak-to-peak roughness of less than approximately 4 nm, the second surface arranged on a side of the semiconductor layer sequence that is remote from the first surface, wherein material applied by the ion assisted application method is one of: wherein the second surface comprises a radiation exit area, wherein the applying the at least one layer on the first surface consists of applying a plurality of layer pairs, each of said layer pairs consisting of a first layer and a second layer, wherein the applying the at least one layer on the second surface consists of applying a plurality of layer pairs, each of said layer pairs consisting of a first layer and a second layer, wherein each first layer consists of tantalum pentoxide, wherein each second layer comprises silicon dioxide, wherein each of the first and second layers has a thickness of approximately a quarter of the wavelength of the electromagnetic radiation emitted by the active region of the semiconductor layer sequence, and wherein a number of layer pairs on the second surface is less than a number of layer pairs on the first surface.
