Abstract
For semiconductor chips using thin film technology, an active layer sequence is applied to a growth substrate, on which a reflective electrically conductive contact material layer is then formed. The active layer sequence is patterned to form active layer stacks, and reflective electrically conductive contact material layer is patterned to be located on each active layer stack. Then, a flexible, electrically conductive foil is applied to the contact material layers as an auxiliary carrier layer, and the growth substrate is removed.
