Claim Text:
1. A fabrication apparatus for fabricating a layer structure comprising at least a patterned first layer and a patterned second layer on a substrate, wherein a layer structure with an unpatterned first layer and an unpatterned second layer are provided on the substrate, the unpatterned first layer being located between the substrate and the unpatterned second layer, the fabrication apparatus comprising: a protective material application unit for applying protective material at least on parts of the provided layer structure for protecting at least the parts of the provided layer structure, an etch mask application unit for applying a patterned etch mask on the unpatterned second layer after the protective material has been applied, an etching unit for etching the unpatterned second layer for forming the patterned second layer, an ablation unit for ablating the unpatterned first layer through the protective material such that the patterned first layer is generated, and a protective material removing unit for removing the protective material.
