摘要:
A method of producing an optoelectronic semiconductor chip includes providing a growth substrate, producing a III nitride nucleation layer on the growth substrate by sputtering, wherein a material of the growth substrate differs from a material of the nucleation layer, and growing a III nitride semiconductor layer sequence having an active layer onto the nucleation layer.
