Abstract

Official abstract text for this publication.

A positive resist composition comprises: (A) a resin of which solubility in an alkali developer increases under an action of an acid; (B) a compound capable of generating an acid upon irradiation with actinic rays or radiation; (C) a resin having at least one of a fluorine atom and a silicon atom; and (D) a solvent; and a pattern forming method using the positive resist composition.

First claim

Opening claim text (preview).

What is claimed is: 1. A positive resist composition, which comprises: (A) a resin of which solubility in an alkali developer increases under an action of an acid; (B) a compound capable of generating an acid upon irradiation with actinic rays or radiation; (C) a resin having at least one of a fluorine atom and a silicon atom; and (D) a solvent, wherein: the amount added of the resin (C) is 0.1 to 6.0 mass %, based on the entire solids content of the positive resist comp…
