Lithographic or similar techniques are used, either directly onto a metal mounted on the substrate, or onto a mold which then is used to impress the metal. In a preferred embodiment, a trench or series of nano-sized trenches are formed in the metal. 2004 published US patent 6,680,214 Tavkhelidze A., Edelson J. S., Cox I.
