    摘要: A double pattern is formed by coating a first positive resist composition onto a substrate, patternwise exposure to radiation, and development with alkaline developer to form a first resist pattern; applying heat and/or radiation to render the first resist pattern insoluble in a second solvent and in a second developer; coating a second resist composition on the first resist pattern, patternwise exposure to radiation, and development with second developer to form a second resist pattern. The resin in the first resist composition comprises recurring units of formula (1) wherein R1 is H, CH3 or CF3, m=1 or 2, n=0 or 1.

    摘要: A resist composition is provided comprising a silicone resin, a photoacid generator, a nitrogen-containing organic compound, and a solvent. The silicone resin is obtained through cohydrolytic condensation of a mixture of three silane monomers containing a norbornane group having hexafluoroisopropyl alcohol, an organic group having a carboxyl group protected with an acid labile group, and a lactone ring-bearing organic group, respectively. The resist composition has satisfactory resolution and overcomes the problem of a low selective etching ratio between resist film and organic film during oxygen reactive etching.
