- Abstract
- Currently, there are many ongoing research efforts to utilize printed electronics in commercialization field. Since the quality of electronic devices made by printed electronics technique is highly influenced by the printing quality, printability is one of the most important factor. Therefore, in this work, several Cu nano-inks were fabricated in respect to wt% of poly(N-vinylpyrrolidone) (PVP) to investigate the printability. Also, the printed Cu nano-film was sintered using a flash light sintering method with controlling various sintering conditions to analyze correlation between printability and sinterability. The un-sintered and sintered Cu nano-films were characterized using various techniques such as 4-point probe method, 2-D profiler, and scanning electron spectroscopy (SEM). From these results, it was noticeable that the high uniformness of printing and low resistivity of 20.1 μΩ·cm were successfully accomplished about Cu nano-ink of 3 wt% PVP and 4 J/cm2 of flash light sintered (1 pulse, 5 ms pulse duration) case.
