Ultra-precise printing of conductive lines in nano-scale
Printing of nanomaterials is not new. The methods available on the market, which are continually being developed, include INKJET (printing using nano-ink), ESJET (electrostatic inkjet printing) and EHD (electrohydrodynamic printing). However, XTPL's new method represents a major breakthrough in this sector. Our company has patented and is commercialising a guided assembly of nanoparticles for creating (or, to put it simply, printing) conductive lines with a width of as little as 100 nm. XTPL's new comprehensive method for nano-scale printing of conductive lines is characterised by extraordinary flexibility, precision and low cost. During the process of line formation, the printing head deposits a properly formulated ink - nanoparticles in a mixture of solvents - on any non-conductive substrate (even one that is not flat). An external electric field (only ~1 V to ~10 V) causes nanoparticles to assemble in a clearly defined and controlled way to form a line (100 nm to 3 μm). The process takes place between a stationary and movable electrode, which guides the formation of the line. Printing in terms of XTPL's technology means composing nanoparticles on a substrate. The disruptive technology of XTPL is protected by an international patent application.
