Abstract

We present laser-induced forward transfer of solid-phase polymer films, shaped using a Digital Micromirror Device (DMD) as a variable illumination mask. Femtosecond laser pulses with a fluence of 200-380 mJ/cm2 at a wavelength of 800 nm from a Ti:sapphire amplifier were used to reproducibly transfer thin films of poly(methyl methacrylate) as small as ~30 μm by ~30 μm with thickness ~1.3 μm. This first demonstration of DMD-based solid-phase LIFT shows minimum feature sizes of ~10μm.
