The invention discloses a method for adhering a metal layer to a polymer substrate and device manufacture therefrom. The metal layer is deposited on a sacrificial substrate of a mold to form part of an interior surface of the mold, and a solution of monomers is deposited on the metal layer. The monomers are then polymerized together to form the polymer substrate on the metal layer. Then the polymer substrate is removed from the mold such that the metal layer is removed from the mold and adhered to the polymer substrate.

Processability of polymeric substrates and related methods

A method of manufacturing an electrical device, comprising: forming a patterned inorganic liftoff layer to expose a target electrode site on a softening polymer layer, depositing an electrode layer on the inorganic liftoff layer and on the exposed target electrode site, and removing the inorganic liftoff layer by a horizontal liftoff etch to leave the electrode layer on the exposed target electrode site.
