  摘要：

  我们描述了由光碱发生器 (PBG)、碱敏感聚合物和碱放大器组成的高灵敏度光聚合物，光碱发生器通过自催化分解释放出胺分子，从而增强了碱敏感聚合物的碱催化反应。由碱放大器产生的低分子量碱分子在聚合物薄膜中广泛扩散，导致低分子量碱物种以 "空气感染 "的方式降低了分辨能力，尽管光敏性得到了增强。为了提高性能，我们设计了一种新型碱基敏感聚合物 (1)，其中的碱基放大单元可自动催化转化为附着在聚合物骨架上的氨基。经 PBG 感光的 1 薄膜在紫外线照射和随后的热处理过程中自动催化分解。这意味着 1 的碱增殖反应不受其聚合物结构的影响。此外，与传统的由 PBG 和碱惰性聚合物组成的化学放大光刻胶相比，用 PBG 感光的 1 薄膜提供了一种可用酸性水溶液显影的正工作光刻胶，并显示出更高的光敏性。此外，与使用低分子量碱放大器的碱敏感光聚合物相比，使用碱放大聚合物 1 可以防止 "空气感染"，并提高依靠碱增殖反应的光聚合物的分辨能力。

  We describe highly sensitive photopolymers consisting of a photobase generator (PBG), a base-sensitive polymer, and a base amplifier that decomposed autocatalytically to release an amine molecule which resulted in the enhancement of base-catalyzed reactions of the base-sensitive polymer. Low molecular weight base molecules produced from the base amplifiers were widely diffused in the polymer film, resulting in the reduction of resolution power in the manner of “air infection” of low molecular weight basic species, although the photosensitivity was enhanced. To improve the performance, we have designed a novel base-sensitive polymer (1) tethering base-amplifying units that autocatalytically transform into amino groups attached to the polymer backbone. A film of 1 sensitized with PBG was decomposed autocatalytically by UV irradiation and subsequent heat treatment. This means that the base proliferation reaction of 1 proceeded regardless of its polymer structure. In addition, a film of 1 sensitized with PBG provided a positive working photoresist developable with an acidic aqueous solution and showed much higher photosensitivity when compared with conventional chemically amplified photoresists comprising PBG and base-labile polymers. Moreover, the use of base-amplifying polymer 1 led to prevention of “air infection”, and improvement in the resolution power of photopolymers relying on base proliferation reactions when compared with base-sensitive photopolymers coupled with low molecular weight base amplifiers.
