Processes for the Self-assembly of Micro Parts

Abstract : The following approach of a fluidic based self-assembly process uses the surface forces for a precise handling and positioning of small devices for a roll-to-roll manufacturing. The surface, on which the device should be positioned, will be functionalized with hydrophile and hydrophobic areas. Thus water droplets can be caught on the hydrophile areas. The devices to be positioned will be placed on these droplets and due to the surface tension moved to their final position. The droplets, a solution of ultrapure water and isopropanol, are evaporating residue-free within seconds [1].
