  A polymerizable anion-containing sulfonium salt having formula (1) is provided wherein R 1 is H, F, methyl or trifluoromethyl, R 2 , R 3 and R 4 are C 1 -C 10 alkyl, alkenyl or oxoalkyl or C 6 -C 18 aryl, aralkyl or aryloxoalkyl, or two of R 2 , R 3 and R 4 may bond together to form a ring with S, A is a C 2 -C 20 hydrocarbon group having cyclic structure, and n is 0 or 1. The sulfonium salt generates a very strong sulfonic acid upon exposure to high-energy radiation. A resist composition comprising a polymer derived from the sulfonium salt is also provided.

  Photoacid generators generate sulfonic acids of formula (1a) or (1c) upon exposure to high-energy radiation. R 1 —COOCH(CF 3 )CF 2 SO 3 + H + (1a) R 1 —O—COOCH(CF 3 )CF 2 SO 3 − H + (1c) R 1 is a C 20 -C 50 hydrocarbon group having a steroid structure. 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）或（1c）的磺酸。R1—COOCH(CF3)CF2SO3+H+(1a)R1—O—COOCH(CF3)CF2SO3−H+(1c)R1是具有类固醇结构的C20-C50烃基。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。

  A sulfonium salt has formula (1) wherein R 1 is a monovalent hydrocarbon group except vinyl and isopropenyl, R 2 , R 3 , and R 4 are alkyl, alkenyl, oxoalkyl, aryl, aralkyl or aryloxoalkyl or may bond together to form a ring with the sulfur atom, and n is 1 to 3. A chemically amplified resist composition comprising the sulfonium salt is capable of forming a fine feature pattern of good profile after development due to high resolution, improved focal latitude, and minimized line width variation and profile degradation upon prolonged PED.

  一种硫铵盐的化学式为（1），其中R1是一种一价碳氢基团，但不包括乙烯基和异丙烯基，R2、R3和R4是烷基、烯基、氧代烷基、芳基、芳基烷基或芳基氧代烷基，或者它们可以相互连接形成与硫原子的环，并且n为1至3。包含该硫铵盐的化学增感抗剂组合物能够由于高分辨率、改善的焦距宽度、以及在长时间PED后最小化线宽变化和剖面降解而形成良好剖面的精细特征图案。

  The photoacid generator produces a sulfonic acid which has a bulky cyclic structure in the sulfonate moiety and a straight-chain hydrocarbon group and thus shows a controlled acid diffusion behavior and an adequate mobility. The PAG is fully compatible with a resin to form a resist composition which performs well during the device fabrication process and solves the problems of resolution, LWR, and exposure latitude.

  照片酸发生剂会产生一种含有笨重环状结构的磺酸基团和直链碳氢基团的磺酸，因此表现出受控的酸扩散行为和适度的活性。该PAG与树脂完全兼容，形成一个抗蚀剂组合物，在器件制造过程中表现良好，并解决了分辨率、LWR和曝光容限等问题。
