Abstract
A method for forming a conductive feature. The method includes providing a substrate and providing a conductive composition. The conductive composition includes metal particles, a non-acid protic solvent, and a high polarity solvent. The non-acid protic solvent and high polarity solvent are present in concentrations sufficient to ionize the non-acid protic solvent and remove oxides when heated. The method further includes heating the composition to a temperature less than about 250° C. to form a conductive feature having less than about ten times the resistivity of bulk copper.
