Abstract

Laser cutting a metal foil by providing a polymer film as a carrier layer for the metal foil where the metal foil is ablated by the laser beam wavelength selected for laser cutting and wherein the polymer film is a polymer film that is transparent to the laser beam wavelength selected for laser cutting such that laser cutting produces metal foil cut parts in a substrate while the polymer backing remains intact for supporting the cut parts for subsequent separation of the cut parts from substrate.
