  • Publication number: 20090256287
    Abstract: Radiation-curable silsesquioxane resin materials are employed for micro- and nanolithography. The resin materials can include a radiation-curable silsesquioxane resin and a photo-initiator having low viscosity. The low viscosity of the liquid system allows imprinting with low pressure and low temperature; e.g. room temperature. The resist's dry etching resistance is increased and the cured film is more easily separated from the mask. Due to its high modulus after cure, the material allows the fabrication of micro- and nano-features having high aspect ratios while providing a high throughput. Various pattern sizes, for example, ranging from tens of microns to as small as a few nanometers, may be achieved with the UV-curable material system.
