    摘要: A pattern is formed by coating a first positive resist composition comprising a base resin, a photoacid generator, and a base generator having both a 9-fluorenylmethyloxycarbonyl-substituted amino group and a carboxyl group onto a substrate to form a first resist film, patternwise exposure, PEB, and development to form a first resist pattern, heating the first resist pattern for causing the base generator to generate a base for inactivating the pattern to acid, coating a second positive resist composition comprising an alcohol and an optional ether onto the first resist pattern-bearing substrate to form a second resist film, patternwise exposure, PEB, and development to form a second resist pattern.

    摘要: A negative pattern is formed by applying a resist composition onto a substrate, prebaking, exposing to high-energy radiation, baking (PEB), and developing the exposed resist film in an organic solvent developer to dissolve the unexposed region of resist film. The resist composition comprising a polymer comprising recurring units having an acid labile group-substituted carboxyl group and/or hydroxy group and recurring units having an oxirane or oxetane ring, an acid generator, and an organic solvent displays a high dissolution contrast in organic solvent development and controlled acid diffusion. A fine hole pattern featuring good size control can be formed.

    摘要: A polymer obtained from copolymerization of a recurring unit having a carboxyl group and/or phenolic hydroxyl group substituted with an acid labile group with a methacrylate having a phenolic hydroxyl-bearing pyridine is useful as a base resin in a positive resist composition. The resist composition comprising the polymer is improved in contrast of alkali dissolution rate before and after exposure, acid diffusion control, resolution, and profile and edge roughness of a pattern after exposure.

    摘要: A negative pattern is formed by coating a resist composition onto a substrate, exposure, bake, and development in alkaline water. The resist composition comprises a polymer comprising acid labile group-containing recurring units, adapted to turn soluble in alkaline developer under the action of acid, an acid generator and/or an acid, a photobase generator capable of generating an amino-containing compound, a quencher for neutralizing acid for inactivation, and an organic solvent.

    摘要: A pattern is formed by coating a resist composition comprising a polymer comprising recurring units having an optionally acid labile group-substituted naphthol group, an acid generator, and an organic solvent onto a substrate, baking to form a resist film, exposing the resist film to high-energy radiation, baking, and developing the exposed film with an organic solvent developer to form a negative pattern wherein the unexposed region of film is dissolved and the exposed region of film is not dissolved. In the process of image formation via positive/negative reversal by organic solvent development, the resist film has a high dissolution contrast and controlled acid diffusion. By subjecting the resist film to exposure through a mask having a lattice-like pattern and organic solvent development, a fine hole pattern can be formed at a high precision of dimensional control.

    摘要: A resist composition is provided comprising a polymer comprising recurring units having a protected hydroxyl group, a photoacid generator, an organic solvent, and a hydroxyl-free polymeric additive comprising fluorinated recurring units. A negative pattern is formed by coating the resist composition, prebaking to form a resist film, exposing, baking, and developing the exposed film in an organic solvent-based developer to selectively dissolve the unexposed region of resist film.
