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 positive resist composition comprising a polymer having carboxyl groups substituted with an acid labile group having formula (1) exhibits a high contrast of alkaline dissolution rate before and after exposure, a high resolution, a reduced acid diffusion rate, and forms a pattern with good profile, minimal edge roughness, and etch resistance. In formula (1), R1 and R2 each are alkyl, aryl, or alkenyl, which may contain oxygen or sulfur, R3 is fluorine or trifluoromethyl, and m is an integer of 1 to 5.

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.
