Abstract: PROBLEM TO BE SOLVED: To provide a chemically amplifying positive or negative radiation sensitive composition capable of stably forming a fine pattern excellent in machining performance in a small space, critical dimension uniformity, maintainability and stability as a resist, having small density dependence in high accuracy. SOLUTION: The positive type radiation sensitive component contains (A1) a copolymer including a hydroxy(methyl) styrene unit and/or an alkoxy(methyl) styrene unit and a repeating unit expressed in formula (3) and (B) a radiation sensitive acid generator. The negative type radiation sensitive component contains (A2) a copolymer including a hydroxy(methyl) styrene unit and a repeating unit expressed in the formula (3), (B) the radiation sensitive acid generator and (C) a compound capable of bridging the component of (A2) under the existence of an acid.

Abstract: PROBLEM TO BE SOLVED: To provide a radiation-sensitive resin composition having high resolution, as well as, being useful as a chemically amplified resist having superior LER. SOLUTION: The radiation-sensitive resin composition contains an alkali-insoluble or slightly alkali-soluble resin containing a repeating unit having a lactone skeleton, an acid generator capable of generating benzenesulfonic acid, and an acid generator comprising a compound, having a structure of Formula (I-A) or Formula (I-B), wherein Z 1 and Z 2 are mutually independently F, or a 1-10C linear or branched perfluoroalkyl group; Y 1 is a single bond or a divalent bond group; R is a substituent; k is an integer of 0-5; n is an integer of 0-5; and if a plurality of symbols R exist, they may bond with each other to form a ring.
