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.
提供了具有
硅含基团且在193纳米处透明的可聚合单体;以及
乙烯基不饱和基团。这些单体形成的聚合物可用于制备具有
化学增感、辐射敏感的双层光阻的亚100纳米图像的工艺中。双层光阻被放置在基底上,包括(i)顶部成像层,包括辐射敏感的酸发生剂和(ii)有机底层。该双层光阻可用于集成电路的制造。
