    • There is provided a composition for forming anti-reflective coating for use in a lithography which has a high effect of inhibiting reflected light, causes no intermixing with resist layers, affords excellent resist patterns, has a higher dry etching rate compared with the resist, and has broader margin of depth of focus and higher resolution than the prior compositions.Concretely, the composition is one for forming anti-reflective coating for use in a lithographic process in manufacture of a semiconductor device, and comprises a resin containing a lactone structure. The resin is one which a γ-lactone structure or a δ-lactone structure is introduced to a main chain thereof or a side chain bonded to the main chain.
    • 提供了一种用于形成抗蚀涂层的组合物,其具有抑制反射光的高效果,不会与抗蚀剂层混合,提供优异的抗蚀剂图案,与抗蚀剂相比具有更高的干蚀刻速率,以及 具有比现有组合物更宽的焦点深度和更高的分辨率。 具体地,该组合物是用于形成用于制造半导体器件的平版印刷工艺中的抗反射涂层的组合物,并且包含含有内酯结构的树脂。 树脂是将γ-内酯结构或δ-内酯结构引入其主链或与主链结合的侧链的树脂。
