Abstract:
1. A method for simultaneous manufacture of a plurality of semiconductor chips for optoelectronics having an active thin-film layer wherein a photon-emitting active zone is formed, comprising the steps of: epitaxially growing a layer sequence containing a photon-emitting zone on a growth substrate wafer; forming at least one cavity in the layer sequence such that a plurality of mesas are formed in the layer sequence, said mesas being connected by connecting portions including at least a portion of said photon-emitting zone; applying at least one insulating layer onto a surface of the layer sequence provided with cavities; producing at least one through-contacting on the mesas; applying a wafer composite including the growth substrate wafer and the layer sequence onto a carrier substrate wafer such that the mesas face toward the carrier substrate wafer; uniting the wafer composite with the carrier substrate wafer; at least partially removing the growth substrate wafer; applying an electrical contact onto a side of the layer sequence lying opposite the mesas; and dividing a wafer composite of the carrier substrate wafer and the structured layer sequence along parting tracks to form semiconductor chips, each of the semiconductor chips including a light emitting diode having a plurality of the mesas.
