Novel fabrication technique for nanoscale hydrogen silsesquioxane structures using a direct printing technique

Hydrogen silsesquioxane (HSQ), a type of spin-on glass, is an attractive material for nanobio, semiconductor and photoelectronic applications because it can be transformed into SiO₂ by a simple annealing process. Studies on the fabrication of nanosized structures are necessary for the simple and easy production of HSQ nanostructures because of their unique characteristics. In this study, a fabrication method was developed for HSQ nanostructures as small as 50 nm using a direct printing technique with a poly (dimethylsiloxane) (PDMS) mold. Using this technique, HSQ nanostructures can be fabricated on a curved substrate
