Laser Lift-Off Process for Additive Micropatterning of Functional Particles and Films

Laser lift-off is one of potential candidates for new additive manufacturing technologies since it would realize additive patterning in micron/submicron resolution under atmospheric and room-temperature conditions. We have developed a variety of laser lift-off processes towards electronics, bio-sensing and medical treatments. In this paper, two kinds of laser lift-off methods were introduced: $\underline{L}$aser-$\underline{I}$nduced $\underline{D}$ot $\underline{T}$ransfer (LIDT) for micro/nanodots printing and $\underline{L}$aser-$\underline{I}$nduced $\underline{F}$orward $\underline{T}$ransfer with $\underline{o}$ptical stamp (LIFTop) for micropatterning of various functional films.
