Abstract: PROBLEM TO BE SOLVED: To provide a polymerizable monomer which has an ethylenically unsaturated group and silicon-containing groups transparent at 193 nm. SOLUTION: This polymerizable monomer has a polymerizable ethylenically unsaturated group and a plurality of silicon-containing groups separated from each other by groups X having no reactivity and transparent at 193 nm. A polymer obtained from the monomer can be used in the process for forming an image of 100 nm or lower by using a chemically amplified radiation-sensitive bilayer resist. The bilayer resist is arranged on a substrate and comprises (1) an upper image formation layer containing a radiation-sensitive acid-generating agent and (2) an organic lower layer. This bilayer resist can be used for producing integrated circuits.

Abstract: PROBLEM TO BE SOLVED: To obtain a polymerizable monomer having Si-containing groups, transparent at 193 nm and ethylenically unsaturated group.
SOLUTION: The polymerizable monomer has the Si-containing groups separated each other by a group X transparent at 193 nm and having no reactivity and has the ethylenically unsaturated group. Polymers obtained from the monomer can be used in processes for forming sub-100 nm images by using 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 production of integrated circuits.
