Polymerizable monomers having silicon containing groups that are transparent at 193 nm; and ethylenically unsaturated group are provided. Polymers from these monomers can be used in processes for forming sub-100 nm images with a chemically amplified, radiation sensitive bilayer resist. The bilayer resist is disposed on a substrate and comprises (i) a top imaging layer comprising a radiation sensitive acid generator and (ii) an organic underlayer. The bilayer resist can be used in the manufacturing of integrated circuits.
