摘要:
In an embodiment a method includes arranging a first semiconductor wafer above a carrier, wherein the first semiconductor wafer includes a plurality of first semiconductor optoelectronic components, separating a plurality of the first components from the first semiconductor wafer by laser radiation so that the first components fall onto the carrier and attaching the first components separated from the first semiconductor wafer to the carrier, wherein regions of the first semiconductor wafer between adjacent first components are thinned and the first components are covered with a passivation layer before the first components are separated from the first semiconductor wafer.
