Abstract
A conductive paste composition comprises (i) an inorganic powder comprising at least a conductive powder, (ii) at least one microgel polymer, and (iii) a solvent. The paste composition may be used in a process for manufacturing an electrical device comprising: preparing a substrate; applying the conductive paste onto the substrate in a preselected pattern; and heating the applied conductive paste to form a conductive structure that provides an electrode for connecting the device. The paste composition beneficially permits the formation of narrow, high aspect ratio features in the conductive structure.
