Patent ID: 6971165

Claim:
A method for manufacturing a pair of electrodes comprising the steps of: (a) depositing islands of an oxidizable metal over pre-determined regions of a substantially flat first electrode; (b) depositing a layer of a second electrode material over a surface of the first electrode, which is deep enough to cover said islands; (c) separating the first electrode from the layer of a second electrode material to expose the islands of the oxidizable metal on the first electrode; (d) oxidizing the islands of oxidizable metal, which causes the islands to expand and form expanded islands; (e) contacting the expanded islands on the first electrode with the layer of the second electrode material, whereupon a gap is formed between the first electrode and the layer of second electrode material; wherein the first electrode and the layer of second electrode material form a pair of electrodes in which any imperfections on the surface of the first electrode are matched in said layer of second electrode material.
