    • Novel methods of double patterning a photosensitive resin composition are provided. The methods involve applying the photosensitive composition to a substrate and thermally crosslinking the composition. The crosslinked layer can be used to provide reflection control. Upon exposure to light, the crosslinked polymer (or oligomer or monomer) in the compositions will decrosslink, rendering the light-exposed portions soluble in typical photoresist developing solutions (e.g., alkaline developers). Advantageously, the crosslinked portions of the composition remain insoluble in the solvent used to form the photosensitive composition. As a result, the coating, lithographic, and or developing steps can be repeated multiple times in varying order, depending upon the particular process, without destroying earlier-formed patterns.
    • 提供了双重图案化感光性树脂组合物的新方法。 所述方法包括将光敏组合物施加到基底上并使组合物热交联。 交联层可用于提供反射控制。 在曝光时,组合物中的交联聚合物(或低聚物或单体)将脱链,使光曝光部分可溶于典型的光致抗蚀剂显影溶液(例如碱性显影剂)。 有利地,组合物的交联部分保持不溶于用于形成光敏组合物的溶剂中。 结果,涂层,光刻和/或显影步骤可以根据特定的工艺以不同的顺序重复多次,而不会破坏早期形成的图案。

    • Acid-sensitive, developer-soluble bottom anti-reflective coating compositions are provided, along with methods of using such compositions and microelectronic structures formed thereof. The compositions preferably comprise a crosslinkable polymer dissolved or dispersed in a solvent system. The polymer preferably comprises recurring monomeric units having adamantyl groups. The compositions also preferably comprise a crosslinker, such as a vinyl ether crosslinking agent, dispersed or dissolved in the solvent system with the polymer. In some embodiments, the composition can also comprise a photoacid generator (PAG) and/or a quencher. The bottom anti-reflective coating compositions are thermally crosslinkable, but can be decrosslinked in the presence of an acid to be rendered developer soluble.
    • 提供了酸敏感的,显影剂可溶的底部抗反射涂料组合物,以及使用这些组合物的方法和由其形成的微电子结构。 组合物优选包含溶解或分散在溶剂体系中的可交联聚合物。 聚合物优选包含具有金刚烷基的重复单体单元。 组合物还优选包含与聚合物分散或溶解在溶剂体系中的交联剂,例如乙烯基醚交联剂。 在一些实施方案中,组合物还可以包含光酸产生剂(PAG)和/或猝灭剂。 底部抗反射涂层组合物是可热交联的,但可以在酸的存在下去交联以使显影剂可溶。
