In one aspect, organic coating compositions, particularly antireflective coating compositions, are provided that comprise that comprise a diene/dienophile reaction product. In another aspect, organic coating compositions, particularly antireflective coating compositions, are provided that comprise a component comprising a hydroxyl-naphthoic group, such as a 6-hydroxy-2-naphthoic group Preferred compositions of the invention are useful to reduce reflection of exposing radiation from a substrate back into an overcoated photoresist layer and/or function as a planarizing, conformal or via-fill layer.
一方面,有机涂层组合物,尤其是减反射涂层组合物,包含二烯/亲二烯反应产物。在另一方面,提供的有机涂层组合物,尤其是抗反射涂层组合物,包含一个由羟基-萘基(如 6-羟基-2-萘基)组成的组分。 本发明的优选组合物有助于减少曝光辐射从基底反射回涂层光刻胶层和/或用作平面化、保形或通孔填充层。
