Abstract

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