Abstract:
1. An optoelectronic semiconductor device comprising a semiconductor chip, a carrier substrate and a foil, wherein the semiconductor chip has an active layer that generates radiation, the carrier substrate has a first electrically conductive contact track and a second electrically conductive contact track on a top side, the semiconductor chip is arranged on the top side of the carrier substrate, the foil is arranged at least in regions on a radiation exit side of the semiconductor chip, said radiation exit side being remote from the carrier substrate and on the top side of the carrier substrate, the foil has at least one electrically conductive first conductor track at least in regions on a top side remote from the carrier substrate, and the foil has at least one first perforation and at least one second perforation arranged such that the semiconductor chip can be electrically contact-connected to the first contact track of the carrier substrate via the first conductor track of the foil, the carrier substrate has a cutout in which the semiconductor chip is arranged, the foil extends into the cutout when seen in a top view, a bottom and sidewalls of the cutout are free of the foil, an electrical contact-connection between the semiconductor chip and the first conductor track is in the form of contact drops located in a respective perforation of the foil, the contact drops project beyond a height of the perforations and completely fill the perforation, and a material of the contact drops differs from a material of the first conductor track.
