Fabricating high-density integrated circuits require three dimensional electrode lines with high aspect-ratio. Nowadays, many electrode lines for electronic circuits are fabricated by printing technologies to give simple and environmental friendly fabrication technique. However, most applications of printing technologies are in two dimensional structures. In this study, we propose printing technology to fabricate three dimensional electrode lines. Electrohydrodynamic (EHD) jet printing with printing speed up to 800 mm/s was used to make three dimensional electrode lines with aspect ratio greater than 5 by using multiple printing methods. Two kinds of NPK silver inks with viscosity 5000 and 8000 cP were used. Parametric studies were done to observe the effect of printing parameters, i.e. printing numbers and printing speed into the aspect ratio of the lines. The results showed that increasing printing numbers and printing speed could increase the aspect ratio of lines. The high aspect ratio lines conducted by this study have great potential to improve efficiency of solar cells.
