Abstract
Methods for patterning a metal over a substrate and devices formed using the methods are disclosed. A patterned die having at least one raised portion and having a metal layer over the die is pressed onto a thin metal film over a substrate, such that the metal layer over the raised portion of the patterned die contacts portions of the thin metal film. Pressure is then applied such that the metal layer and the thin metal film cold-weld to one another. The patterned die is removed, such that the portions of the metal layer cold-welded to the thin metal film break away from the die and remain cold-welded to the thin metal film over the substrate, in substantially the same pattern as the patterned die.
