Abstract: Provided is a composition for resist patterning comprising a thiol; at least one -ene monomer; at least one polymerization initiator; and, optionally, a metal oxide used in an amount of 0.1 to 50 wt. % per weight of the composition; the thiol and -ene monomer are used in a stoichiometric ratio with a refractive index between 1.6 and 1.8. The composition is used in a patterning process wherein the composition is dispensed to the substrate, is covered with a mask, and is cured, e.g., by UV radiation, at room temperature with light having a wavelength in the range of 200 nm to 450 nm. The process may be carried out with thermal annealing.

Abstract: A simple and practical method that can reduce the feature size of a patterned structure bearing surface hydroxyl groups is described. The patterned structure can be obtained by any patterning technologies, such as photo-lithography, e-beam lithography, nano-imprinting lithography. The method includes: (1) initially converting the hydroxyl or silanol-rich surface into an amine-rich surface with the treatment of an amine agent, preferably a cyclic compound; (2) coating an epoxy material on the top of the patterned structure; (3) forming an extra layer when applied heat via a surface-initiated polymerization; (4) applying an amine coupling agent to regenerate the amine-rich surface; (5) coating an epoxy material on the top of the patterned structure to form the next layer; (6) repeating step 4 and 5 to form multiple layers; This method allows the fabrication of feature sizes of various patterns and contact holes that are difficult to reach by conventional lithographic methods.
