ABSTRACT:
A process including: (a) forming a feature comprising uncoalesced silver-containing nanoparticles; (b) heating the uncoalesced silver-containing nanoparticles to form coalesced silver-containing nanoparticles wherein the feature comprising the coalesced silver-containing nanoparticles exhibits a low electrical conductivity; and (c) subjecting the coalesced silver-containing nanoparticles to an acid-containing composition to increase the electrical conductivity of the feature by at least about 100 times.
