    Abstract: PROBLEM TO BE SOLVED: To provide a radiation sensitive resin composition having high transparency for radiation and excellent basic physical properties as a resist such as sensitivity, resolution, dry etching durability and pattern profile. SOLUTION: The radiation sensitive resin composition contains the following resin (A) and (B) a radiation sensitive acid generator. The resin (A) is an alkali insoluble or alkali hardly soluble resin and changed into alkali-soluble by the action of an acid and the resin is, for example, a mevalonic lactone methacrylate/3-hydroxy-1-adamantyl methacrylate/1-methylcyclopentyl alkali methacrylate copolymer, a mevalonolactone methacrylate/3-hydroxyl-1-adamantyl methacrylate/[1-(2-methyl-2-norbornyl)ethoxycarbonyl]methacrylate copolymer.

    Abstract: PROBLEM TO BE SOLVED: To provide a radiation-sensitive resin composition having high transparency for radiation, excellent basic performances as a resist such as sensitivity, resolution, dry etching durability, pattern profile, and suitable as a chemical amplification type resist having high resolution property in a fine pattern region. SOLUTION: The radiation-sensitive resin composition contains (A) a resin which contains a norbornene-based repeating unit derived from 5-(2-methyl-2- adamantyl)oxycarbonylbicyclo[2.2.1]hept-2-ene, 5-(1-methyl-1-cyclopentyl) ocycarbonylbicyclo[2.2.1]hept-2-ene or the like and a (meth)acrylate-based repeating unit derived from 3-hydroxy-1-adamantyl(meth)acrylate, 1-methyl-1- cyclohexyl(meth)acrylate or the like and which is converted into alkali-soluble by the effect of an acid, and (B) a radiation-sensitive acid generator.
