摘要： The present invention provides a polymer that can be used as an anti-refelctive coating (ARC) polymer, an ARC composition comprising the same, methods for producing the same, and methods for using the same. The polymer of the present invention is particularly useful in a submicrolithographic process, for example, using KrF (248 nm), ArF (193 nm), or F2 (157 nm) laser as a light source. The polymer of the present invention comprises a chromophore that is capable of absorbing light at the wavelengths used in a submicrolithographic process. Thus, the ARC of the present invention significantly reduces or prevents back reflection of light and the problem of the CD alteration caused by the diffracted and/or reflected light. The ARC of the present invention also significantly reduces or eliminates the standing wave effect and reflective notching. Therefore, the polymer of the present invention can be used to produce a stable ultrafine pattern that is suitable in manufacturing of 64 M, 256 M, 1 G, 4 G and 16 G DRAM semiconductor devices. Moreover, the ARC of the present invention significantly improves the production yield, of such semiconductor devices.
摘要翻译：本发明提供可用作抗反射涂层（ARC）聚合物的聚合物，包含其的ARC组合物，其制备方法及其使用方法。本发明的聚合物在亚微光刻工艺中特别有用，例如使用KrF（248nm），ArF（193nm）或F2（157nm）激光作为光源。本发明的聚合物包括能够吸收在亚微光刻工艺中使用的波长的光的发色团。因此，本发明的ARC显着地减少或防止了光的反射和由衍射光和/或反射光引起的CD改变的问题。本发明的ARC还显着地减少或消除驻波效应和反射性切口。因此，本发明的聚合物可用于制备适合于制造64M，256M，1G，4G和16G DRAM半导体器件的稳定超细晶格。此外，本发明的ARC显着提高了这种半导体器件的生产成本。
