Problem Addressed

Lateral resolution of conventional printing methods is in general limited to 10-100 µm, which remains as a main challenge toward high performance electronics. For example, inkjet is limited by the size of the droplet ejected from the nozzle aperture; due to the limiting strength and frequency of transducers compared to the force required to eject smaller liquid droplets. The resolutions of screen printing and gravure are strongly restricted by the key geometrical parameters of printing tools, such as the woven mesh openings in screen printing stencil and volume of the engraved cells in gravure cylinder. Although elastomeric stamp features can easily be reduced to nanometer range using replica molding techniques, flexography is also limited because of the contact-mediated liquid instabilities and spreading.
