Abstract

A method and structure for enhancing electromagnetic barrier properties including a substrate, a metallic layer deposited upon the substrate by vacuum metalization, and a plurality of sets of patterns microembossed upon the surface of the metallic layer for increasing the barrier properties of the structure. The plurality of sets of microembossed patterns each have a line density between about 100 and 50,000 lines per square centimeter.
