  • Publication number: 20190155162
    Abstract: A pattern-forming method comprises forming a prepattern that is insoluble or hardly soluble in an organic solvent. A first composition is applied on at least lateral faces of the prepattern to fort i a resin layer. Adjacent regions to the prepattern of the resin layer are insolubilized or desolubilized in the organic solvent without being accompanied by an increase in a molecular weight by heating the prepattern and the resin layer. Regions other than the adjacent regions insolubilized or desolubilized of the resin layer are removed with the organic solvent. The first composition comprises a first polymer having a solubility in the organic solvent to be decreased by an action of an acid. At least one selected from the following features (i) and (ii) is satisfied: (i) the first polymer comprises a basic group; and (ii) the first composition further comprises a basic compound.

    Abstract: A film-forming material for a resist process includes: a siloxane polymer component including at least two selected from the group consisting of a sulfur atom, a nitrogen atom, a boron atom and a phosphorus atom; and organic solvent. The siloxane polymer component preferably has a formulation represented by formula (1). R1 represents a monovalent organic group comprising at least one of a sulfur atom and a nitrogen atom. R2 represents a monovalent organic group comprising at least one of a sulfur atom and a nitrogen atom, a hydrogen atom, a hydroxy group, or a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms. A pattern-forming method includes: applying the film-forming material for a resist process onto a substrate to form a silicon-containing film; forming a pattern using the silicon-containing film as a mask; and removing the silicon-containing film.

  • Patent number: 9329478
    Abstract: A polysiloxane composition includes a polysiloxane, and a first compound. The first compound includes a nitrogen-containing heterocyclic ring structure, and a polar group, an ester group or a combination thereof. A pattern-forming method includes coating the polysiloxane composition on a substrate to be processed to provide a silicon-containing film. A resist composition is coated on the silicon-containing film to provide a resist coating film. The resist coating film is selectively irradiated with a radioactive ray through a photomask to expose the resist coating film. The exposed resist coating film is developed to form a resist pattern. The silicon-containing film and the substrate to be processed are sequentially dry etched using the resist pattern as a mask.

  • Patent number: 8501385
    Abstract: A positive-tone radiation-sensitive composition is used in a resist pattern-forming method as a first positive-tone radiation-sensitive composition. A positive-tone radiation-sensitive composition includes a polymer, a photoacid generator, and a solvent. The polymer includes an acid-labile group and a crosslinkable group. The resist pattern-forming method includes providing the first positive-tone radiation-sensitive composition on a substrate to form a first resist pattern on the substrate. The first resist pattern is made to be inactive to light or heat so that the first resist pattern is insoluble in a second positive-tone radiation-sensitive composition. The second positive-tone radiation-sensitive composition is provided on the substrate to form a second resist pattern on the substrate on which the first resist pattern is formed.
