Abstract
In an embodiment, a substrate made of a first material and having a surface is provided. A first and second nozzle dispense a first solvent paste including electrically conductive nanoparticles and a second solvent paste including non-conductive nanoparticles respectively while moving over the surface of the substrate. The first and second nozzles additively deposit a uniform layer comprising sequential and contiguous zones alternating between the first solvent paste and the second solvent paste. Energy is applied to the nanoparticles to sinter together the nanoparticles and diffuse the nanoparticles into the substrate. The sintered nanoparticles form a layer composed of an alternating sequence of electrically conductive zones contiguous with electrically non-conductive zones.
