Polymerizable monomers having silicon containing groups that are transparent at 193 nm; and ethylenically unsaturated group are provided. Polymers from these monomers can be used in processes for forming sub-100 nm images with a chemically amplified, radiation sensitive bilayer resist. The bilayer resist is disposed on a substrate and comprises (i) a top imaging layer comprising a radiation sensitive acid generator and (ii) an organic underlayer. The bilayer resist can be used in the manufacturing of integrated circuits.
提供具有硅含基团且在193纳米时透明的可聚合单体;以及乙烯不饱和基团。从这些单体中制备的聚合物可用于形成具有化学增感、辐射敏感的亚100纳米图像的工艺中。双层抗蚀剂位于基底上,并包括(i)顶部成像层,包括辐射敏感酸发生剂和(ii)有机底层。双层抗蚀剂可用于集成电路的制造。
