Microcapacitors with controlled electrical capacity in the pF-nF range printed by laser-induced forward transfer (LIFT)

Abstract

Micrometric-sized pixels of hybrid organic-inorganic thin films (Ag/parylene-C) have been printed by laser-induced forward transfer (LIFT) on flexible, cost-efficient substrates. Micrometric capacitors have been fabricated by laser printing such pixels together with silver nanoparticles (AgNP) paste. The AgNP paste has been deposited in the shape of square pads, acting as bottom electrode. This combination is suitable to be used in microelectronic circuits, as the electrical components exhibit controllable capacity in the pF-nF range. Electrical characterizations of the printed pixels demonstrate that the capacitors are fully operative and stable over time. Show more
