| 1. A method for manufacturing a pattern of conductive objects, the method comprising:
depositing in a vacuum deposition chamber an electrically conductive material onto a substrate to form a base layer;
applying an electric insulating agent on selective areas of the base layer, wherein the selective areas are substantially
complementary to areas pre-designed to carry the conductive objects;
electroplating the areas pre-desigined to carry the conductive objects with a second electrically conductive layer;
removing the electric insulating agent;
chemically etching so as to remove the base layer from the selective areas and a top layer of the of the second electrically
conductive layer to create the pattern of conductive objects on the substrate; and
after the etching, performing an oxidation reaction to produce a metal-oxide layer on a top surface of the electrically conductive
layer,
wherein the pattern of conductive objects being an array of transparent electrodes, heaters or electromagnetic interference
shields.
