[18p-C103-5] Development of Surface Patterning Technology by Laser-Induced Forward Transfer of Nanoparticles and Functional Thin Films
Keywords:laser-induced forward transfer, particles of metals, oxides and semiconductors, 3D printing
In this talk, we introduce the latest trend of surface patterning technologies based on laser-induced forward transfer (LIFT). LIFT is a method of "transferring substances" by utilizing the high-temperature and/or high-pressure fields generated by laser ablation. In general LIFT process, a single laser pulse was irradiated from the backside of a source film deposited on a transparent carrier, leading to the transfer of the source material onto an opposite receiver substrate driven by the laser ablation. The feature of LIFT is that it does not require vacuum and chemicals and can be applied to various materials such as metals, oxides, semiconductors and even biomaterials. Further, the device configuration is simple. In addition to the world trend of this technology, we report on two kinds of our LIFT techniques: laser-induced dot transfer (LIDT) for flexible writing of various nanoparticles at atmospheric pressure and laser-induced forward transfer with optical stamp (LIFTOP) for transfer of functional films.
