Abstract: A method of producing an optoelectronic semiconductor chip includes providing a growth substrate and a semiconductor layer sequence grown on the growth substrate with a main extension plane including a p-conductive layer, an active zone and an n-conductive layer, removing the semiconductor layer sequence in regions to form at least one aperture extending through the p-conductive layer and the active zone into the n-conductive layer of the semiconductor layer sequence, depositing a protective layer on a side of the semiconductor layer sequence facing away from the growth substrate, depositing an aluminum layer containing aluminum across the entire surface on a side of the semiconductor layer sequence facing away from the growth substrate, removing the growth substrate, and forming a mesa by removing the semiconductor layer sequence at the regions of the protective layer, wherein the protective layer is subsequently freely externally accessible at least in places.

Abstract: A support structure for receiving planar microchips, comprising a planar support substrate and at least two receiving elements. The receiving elements are connected to the carrier substrate and configured in such a way that they detachably hold a flat microchip between the at least two receiving elements in such a way that the microchip can be moved out with a defined minimum force transversely to a support structure plane.
