  A positive resist composition comprises (A) a resin component which becomes soluble in an alkaline developer under the action of an acid and (B) an acid generator. The resin (A) is a polymer comprising recurring units containing a non-leaving hydroxyl group represented by formula (1) wherein R 1 is H, methyl or trifluoromethyl, X is a single bond or methylene, m is 1 or 2, and the hydroxyl group attaches to a secondary carbon atom. The composition is improved in resolution when processed by lithography.

  Photoacid generators generate sulfonic acids of formula ( 1 a) upon exposure to high-energy radiation. ROC(═O)R 1 —COOCH 2 CF 2 SO 3 − H + (1a) RO is OH or C 1 -C 20 organoxy, R 1 is a divalent C 1 -C 20 aliphatic group or forms a cyclic structure with RO. The photoacid generators are compatible with resins and can control acid diffusion and are thus suited for use in chemically amplified resist compositions.

  光酸发生剂在高能辐射作用下生成式（1a）的磺酸。 ROC(═O)R1—COOCH2CF2SO3−H+(1a) RO为OH或C1-C20有机氧基，R1为二价的C1-C20脂肪族基团或与RO形成环状结构。这些光酸发生剂与树脂相容，可以控制酸的扩散，因此适用于化学增感抗蚀组合物的使用。
