Abstract
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.
