    摘要: Vinylphenylpropionic acid derivatives; processes for producing the derivatives; polymers of the same; and radiosensitive resin compositions containing the polymers. The above polymers exhibit low radiation absorption and are useful as the resin component of radiosensitive resin compositions particularly suitable for chemically amplified resists. For example, t-butyl 4-vinylphenylpropionate is produced by (1) reacting t-butyl bromoacetate with tri(n-butyl)phosphine to obtain a quaternary phosphonium salt, (2) reacting this salt with a base to obtain a phosphorus ylide, (3) reacting this ylide with 2,4,6-tris(3′,5′-di-t-butyl-4′-hydroxybenzyl)methyl-styrene to obtain a quaternary phosphonium salt, and (4) hydrolyzing this salt.

    摘要: A radiation sensitive refractive index changing composition comprising (A) a decomposable compound, (B) a non-decomposable compound having a higher refractive index than the decomposable compound (A), (C) a radiation sensitive decomposer and (D) a stabilizer. By exposing this composition to radiation through a pattern mask, the above components (C) and (A) of an exposed portion decompose to create a refractive index difference between the exposed portion and an unexposed portion, thereby forming a pattern having different refractive indices.
