ABSTRACT:
A method and associated substrate is provided for applying a layer or pattern of metal on a substrate. The method includes providing a target substrate, immobilizing a layer of polymeric material on the target substrate, and applying and immobilizing a layer or pattern of metal on the layer of polymeric material on the target substrate using a stamp onto which the layer or pattern of metal has previously been applied, by bringing the stamp into conformal contact with the target substrate.
