METHOD OF FORMING A FEATURE BY DISPENSING A METALLIC NANOPARTICLE COMPOSITION FROM AN INK-JET PRINT HEAD AND A METALLIC NANOPARTICLE COMPOSITION FOR INK-JET PRINTING
A method of forming a feature by dispensing a metallic nanoparticle composition from an ink-jet print head is disclosed. A jetting waveform is applied to piezoelectric actuator to dispense droplets of the metallic nanoparticle composition through nozzle opening. The droplets range in volume between 0.5 picoliter and 2.0 picoliter. The jetting waveform includes an intermediate contraction waveform portion, a final contraction waveform portion after the intermediate contraction waveform portion, and an expansion waveform portion after the final contraction waveform portion. During the intermediate contraction waveform portion, an applied voltage increases from an initial low voltage to an intermediate voltage and then is held at the intermediate voltage. During the final contraction waveform portion, the applied voltage increases from the intermediate voltage to maximum voltage and then is held at the maximum voltage. During the expansion waveform portion, the applied voltage decreases from the maximum voltage to a final low voltage.
