Laser-induced forward transfer with optical stamp for high-quality film printing (Conference Presentation)

For high quality film printing, we have newly developed a laser-induced forward transfer with optical stamp (shortly, LIFTop), that consists of a two-step transfer process. In the first step, functional films were transferred onto a transparent polymer having high adhesiveness and elasticity like PDMS, which we call “optical stamp”. This stamp helps to avoid the transferred film from pattern spread and fracture. Then, the transferred micro-pattern on the optical stamp was further transferred onto a final target. In this talk, metal and transparent conductive oxide film transfer was demonstrated using our new LIFT process.
