    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.

    摘要: A pattern is formed by coating a chemically amplified positive resist composition comprising a resin comprising acid labile group-containing recurring units and a photoacid generator onto a substrate, drying to form a resist film, exposing the resist film to high-energy radiation through a phase shift mask having a lattice-like array of shifters, PEB, developing to form a positive pattern, illuminating or heating the positive pattern to eliminate acid labile groups for increasing alkaline solubility and to induce crosslinking for imparting solvent resistance, coating a reversal film, and dissolving away the positive pattern in an alkaline wet etchant to form a pattern by way of positive/negative reversal.
