Abstract
A method is provided for producing an optoelectronic device, comprising the steps of providing a substrate, applying a nucleation layer on a surface of the substrate, applying and patterning a mask layer on the nucleation layer, growing a nitride semiconductor in a first growth step, wherein webs are laid which form a lateral lattice, wherein the webs have trapezoidal cross-sectional areas in places in the direction of growth, and laterally overgrowing the webs with a nitride semiconductor in a second growth step, to close spaces between the webs.
