Positive resist composition for immersion exposure and pattern-forming method using the same
Abstract:
A positive resist composition for immersion exposure comprises: (A) a resin capable of increasing its solubility in an alkali developer by an action of an acid, and (B) a compound capable of generating an acid upon irradiation with actinic ray or radiation, wherein the acid satisfies conditions of V≧230 and V/S≦0.93 taking van der Waals volume of the acid as V (Å3), and van der Waals surface area of the acid as S (Å2).
