    • Process for producing dimer-free phenolic polymers, particularly novolak polymers produced from cresol mixtures, and photoresist compositions containing such dimer-free novolak polymers. The process comprises reacting phenolic polymers containing phenolic dimers with a capping agent, such as a silylating agent, to cap all of the phenolic hydroxy groups. This reduces the distillation temperature of the capped dimers and renders the capped polymer stable at such distillation temperature. The capped dimers are distilled off, and finally the phenolic polymer is uncapped. Dimer-free novolaks produce scum-free developed photoresist images.
    • 用于生产无二聚体酚醛聚合物,特别是由甲酚混合物制备的酚醛清漆聚合物的方法,以及含有这种无二聚体的酚醛清漆聚合物的光致抗蚀剂组合物。 该方法包括使含有酚二聚体的酚醛聚合物与封端剂如甲硅烷基化试剂反应以封闭所有酚羟基。 这降低了封端二聚体的蒸馏温度,并使封端聚合物在这样的蒸馏温度下稳定。 将封端的二聚体蒸馏出去,最后酚类聚合物不起泡。 无二聚体酚醛清漆产生无浮渣的显影光刻胶图像。
