    摘要: There is disclosed a patterning process including steps of at least: forming a photoresist film on a substrate; exposing the photoresist film to a high energy beam; developing by using a developer; forming a photoresist pattern; and then forming a spacer on the photoresist pattern sidewall, thereby forming a pattern on the substrate, a patterning process, wherein at least the photoresist pattern having the hardness of 0.4 GPa or more or the Young's modulus of 9.2 GPa or more as a film strength is formed, and a pattern is formed on the substrate by forming a silicon oxide film as the spacer on the photoresist pattern sidewall. There can be provided a patterning process without causing a deformation of a resist pattern and an increase in LWR at the time of forming a silicon oxide film on a photoresist pattern.

    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.
