Research on programmable capillary-force self-assembly nanofabrication

The capillary-force which is an extremely important force in the small objects is considered to be one of the most effective driving forces for the micro-nanoscale self-assembly. However, the process of capillary-force self-assembly is usually uncontrollable, which has prevented it from being used in the formation of specific nanoscale devices. In order to explore the fundamentals of capillary-force self-assembly, we analyzed the impact factors of nanostructures suffered by capillary-force and gave a typical general physical model. Then, we studied the complex structures fabrication method based on capillary-force self-assembly, and analyzed its characteristics and limitations. Finally, we proposed a new concept of programmable capillary-force self-assembly to achieve a reliable control of capillary-force, and thus form a new nanofabrication method.
