Wet stamping of microscale periodic precipitation patterns.

Although periodic precipitation (PP) phenomena have long attracted scientific interest, their study has been limited to macroscopic systems and simple geometries. An experimental method was developed that allows the generation of highly regular, microscopic PP patterns of arbitrary geometries. Generic scaling laws were established that related the morphologies and topographies of the PP patterns to the geometrical parameters of the system. It was possible to control PP at the level of stochastic phenomena and thus to induce micropatterns of desired chiralities and to control the propagation of defects in them. A 3D nucleation-and-growth model was developed that faithfully reproduced the patterns observed in experiments.

Fluorinated organic-inorganic hybrid mold as a new stamp for nanoimprint and soft lithography.

In this paper, we fabricated a fluorinated organic-inorganic hybrid mold using a nonhydrolytic sol-gel process which can produce a crack-free mold without leaving any trace of solvent. No special chemical treatment of a release layer is needed because the fluorinated hybrid mold has fluorine molecules in the backbone. The other advantages of the hybrid mold are thermal stability over 300 degrees C. The hybrid mold produced from UV nanoimprint lithography (UV-NIL) was used as a mold for the next UV-NIL and soft lithography without requiring use of an antisticking layer. Various nanometer scale patterns including sub-100 nm patterns could be obtained from the hybrid mold. Nanopatterning processes using this low-cost mold are useful because they preserve the expensive original master.
