Abstract:
A method for producing an optoelectronic component and an optoelectronic component are disclosed. In an embodiment a method includes providing a semiconductor chip having an active region for radiation emission, applying a seed layer on the semiconductor chip, wherein the seed layer includes a first metal and a second metal being different from the first metal, and wherein the second metal is less noble than the first metal, applying a structured photoresist layer directly to the seed layer and applying a solder layer at least to regions of the seed layer which are not covered by the photoresist layer, wherein a ratio of the first metal to the second metal in the seed layer is between 95:5 to 99:1.
