标 题:Onium compounds and methods of synthesis thereof
发明人：LABEAUME PAUL J
权利人:ROHM & HAAS ELECT MAT
摘要:New onium salt compounds and methods for synthesis of such compounds are provided. Preferred methods of the invention include (a) providing an onium salt compound comprising a sulfonate component having an electron withdrawing group; and (b) treating the onium salt compound with a halide salt to form a distinct salt of the onium compound. The present onium compounds are useful as an acid generator component of a photoresist composition.

标题 :Synthesis of photoresist polymer
发明人：TAKEDA TAKANOBU; WATANABE TAMOTSU
权利人:TAKEDA TAKANOBU; WATANABE TAMOTSU; SHINETSU CHEMICAL CO
摘要:A polymer for use in photoresist compositions is synthesized by effecting polymerization reaction to form a polymerization product mixture and subjecting the mixture to molecular weight fractionation by a liquid phase separation technique using a good solvent and a poor solvent. The fractionation step is iterated at least twice, and one iteration of fractionation includes adding a good solvent which is different from the good solvent added in the other iteration of fractionation.
