    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 applying a first positive resist composition onto a substrate, heat treatment, exposure, heat treatment and development to form a first resist pattern; causing the first resist pattern to crosslink and cure by irradiation of high-energy radiation of up to 180 nm wavelength or EB; further applying a second positive resist composition onto the substrate, heat treatment, exposure, heat treatment and development to form a second resist pattern. The double patterning process reduces the pitch between patterns to one half.

    摘要: The invention provides a novel sulfonium salt having at least one acid labile group attached to a phenyl group in a molecule and a normal, branched or cyclic C.sub.1 -C.sub.20 alkylsulfonate anion. The novel sulfonium salt is effective for increasing the dissolution contrast between exposed and unexposed areas. Upon exposure, it generates an alkylsulfonic acid which is a weak acid, minimizing the influence of side reaction and deactivation during PEB step. The sulfonium salt is useful in a chemically amplified positive resist composition which lends itself to fine patterning and features high resolution.

    摘要: A positive resist composition based on a silicone polymer contains a photo acid generator which will decompose to generate an acid upon exposure to radiation. The silicone polymer includes hydroxybenzyl units wherein some OH groups are replaced by t-butoxycarbonyl, t-butoxycarbonylmethyl, trimethylsilyl or tetrahydropyranyl groups. In a first form, the photo acid generator is a specific onium salt having at least one phenyl group with a t-alkoxy, t-butoxycarbonyloxy or t-butoxycarbonylmethoxy substituent. In a second form, the composition further contains a nitrogenous compound. In a third form, the composition further contains a dissolution inhibitor in the form of a specific silicone compound. The composition is sensitive to high energy radiation and has high sensitivity and resolution.
