Claim:
A resist composition comprising: (A) a resin capable of increasing its solubility in an alkali developer by action of an acid and which does not contain a fluorine atom or a silicon atom; (B) a compound capable of generating an acid upon irradiation with actinic ray or radiation; (C) a resin having at least one of a fluorine atom and a silicon atom; and (D) a solvent, wherein the resin (C) has a degree of molecular weight dispersion of 1.3 or less, a weight average molecular weight of 1.0×10 4 or less and contains any one of a phenolic hydroxyl group, a fluorinated alcohol group, a sulfonic acid group, a sulfonamide group, a sulfonylimido group, an (alkylsulfonyl) (alkylcarbonyl)methylene group, an (alkylsulfonyl) (alkylcarbonyl) imido group, a bis(alkylcarbonyl)methylene group, a bis(alkylcarbonyl) imido group, a bis(alkylsulfonyl)methylene group, a bis(alkylsulfonyl) imido group, a tris(alkylcarbonyl)methylene group, and a tris(alkylsulfonyl)methylene group.
