    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 pattern is formed by applying a positive resist composition comprising a polymer comprising 7-oxanorbornane ring-bearing recurring units and acid labile group-bearing recurring units and an acid generator onto a substrate to form a resist film, heat treating and exposing the resist film to radiation, heat treating and developing the resist film with a developer, and causing the resist film to crosslink and cure with the aid of acid and/or heat. A second resist pattern is then formed in the space area of the first resist pattern. The double patterning process reduces the pitch between patterns to one half.
