Abstract:
1. A method, comprising: depositing a thin metal film over a substrate; pressing a patterned die having at least one raised portion and having a metal layer thereover, onto the thin metal film, such that the metal layer over the raised portion of the patterned die contacts portions of the thin metal film over said substrate, and applying sufficient pressure such that the metal layer cold-welds to the thin metal film; and removing the patterned die, such that the metal layer cold-welded to portions of the thin metal film with which it has contact, detaches from said die and remains in contact with the thin metal film over said substrate in substantially the same pattern as the at least one raised portion of the die, thereby forming a patterned metal layer over said substrate.
