Abstract
The laser-induced forward transfer (LIFT) process can print custom conductive patterns from metallic nanoparticles inks, and is therefore a promising technique for the field of microelectronics. A laser pulse, focused through a transparent substrate, is absorbed either by the ink itself or by a thin absorbing layer between the substrate and the film. The interaction propels the ink, which become a jet and can be collected as a droplet on a receiver substrate [1]. Printing overlapping droplets results in a continuous line. If the current throughputs are increased, this technique could be made competitive with other industrial deposition techniques.
