    摘要: A copolymer having a repeating unit represented by the following general formula I and a chemical amplification positive photoresist composition having the copolymer and a photoacid generator. The photoresist can allow for a good pattern shape even though a post-baking is taken in a somewhat delayed time and for a use of any radiation, such as uv light, deep uv light and charged particle beam. Also, it is superior in storage stability and resolution so that it is useful for the high integration of semiconductor devices. The polymer ranges, in polystyrene-reduced average molecular weight, from 1,000 to 1,000,000. The polymer is represented by the following repeating pattern: ##STR1## wherein, R.sub.1, R.sub.2 and R.sub.3 independently represent a hydrogen atom or a methyl; R.sub.4, R.sub.5 and R.sub.6 independently represent a hydrogen atom, an alkyl group, an alkoxy group or a halogen; 1, m, n each is a repeating number satisfying the condition that 0.3

    摘要: This invention relates to a sulfonium salt, including its manufacturing method, which is effectively used as a photoacid initiator or radical photoinitiator during polymerization and a photoacid generator, leaving the protection groups of organic compounds, especially as an useful photoacid generator of the chemically amplified photoresist employed in semiconductor materials. Since the sulfonium salt of this invention, so prepared via one-step reaction between sulfoxide compound and aromatic compound in the presence of perfluoroalkanesulfonic anhydride, has the advantages in that by overcoming some shortcomings of the prior art to prepare the sulfonium salt via two steps using Grinard reagent, this invention may provide a novel sulfonium salt with higher yield which cannot be achieved in the prior art and also to prepare even any conventional sulfonium salt having better yield.
