Abstract:
A method for patterning a metal layer, which comprises:providing a substrate; above the substrate, producing a patterning layer for structuring a structuring pattern; producing the patterning layer with a base layer zone and a sinking layer zone laterally surrounding the base layer zone, the base layer zone having a contour; depositing a metal layer onto the patterning layer; siliciding the metal layer, at least in a region of the metal layer lying on the sinking layer zone such that a metal silicide layer section is formed in the region; and performing an oxidation step such that the metal silicide layer section migrates into the sinking layer zone of the patterning layer and a metal region having a contour that is identical to the contour of the base layer zone remains on the base layer zone.
