A self-strengthening material is provided, the material comprising a polymer matrix having a plurality of chemical amplifiers dispersed throughout the polymer matrix and a plurality of triggerable reservoirs, the triggerable reservoirs capable of releasing at least one activator of the plurality of chemical amplifiers, wherein the plurality of chemical amplifiers reacts with the at least one activator to produce additional activators capable of changing the mechanical properties of the polymer matrix, and thus strengthening the material.

triggers (Body-3) decompose autocatalytically, but the six with secondary triggers (Body-2) are unaffected. Although Body-2 AAs do not decompose autocatalytically, nonaflate acid does catalyze their decomposition. Lithographic evaluation showed that some AAs are capable of simultaneously improving the resolution, line-edge-roughness, and sensitivity of a control EUV photoresist. This simultaneous improvement
合成并研究了十二种氟化酸放大器(AAs)用于暴露于13.5 nm极紫外(EUV)光的光刻胶中。酸增强剂是在酸的存在下分解以通过催化或自催化机理产生更多酸的化合物。这些AA由主体,触发器和酸前体组成。在C中的AA的溶液的热分解率6 d 6 /米,在100℃-ethylphenol(50/50重量%)C通过监测19 F NMR具有和不具有1.2当量。的2,4,6-三吨丁基吡啶。碱存在下的所有AA均根据一级动力学以速率常数k Base分解。速率常数,k在各种温度下,碱产生激活参数ΔH ‡,ΔS ‡和ΔG ‡。活化的焓,Δ ħ,‡,是在一个窄的范围内的16.6-19.1(千卡/摩尔),而激活的熵,Δ小号‡,范围从0到-12(cal /(mol K))。当允许酸在溶液中累积(在没有碱的情况下)时,具有三级引发剂(Body-3)的6个AA会自催化分解,但是具有二级引发剂(Body-2)的6个不受影响。尽管Body-2
