Abstract

According to the present invention, a resist resin having in its structure a specific bridged-bond-containing aliphatic ring, and a resist composition comprising the same are provided. By using this resist composition, a resist pattern excellent in both transparency against short-wavelength light and dry-etching resistance can be formed by alkali development with high resolution.
