Abstract: Antireflective compositions are provided that contain a basic additive material. Such use of a basic material can significantly decrease or even completely eliminate notching of an overcoated photoresist relief image. Antireflective formulations of the invention are preferably crosslinking compositions and may contain a resin component in addition to the basic additive. Antireflective compositions of the invention can be effectively used at a variety of wavelengths used to expose an overcoated photoresist layer, including 248 nm and 193 nm.

Abstract: New organic-based radiation absorbing compositions are provided that are suitable for use as an antireflective coating composition (“ARC”) for an overcoated photoresist. These compositions also serve effectively as a hard mask layer by exhibiting a sufficient plasma etch selectively from an undercoated dielectric layer.

Abstract: The present invention provides new light absorbing compositions suitable for use as antireflective coating compositions (“ARCs”), particularly for deep UV applications. The antireflective compositions of the invention in general comprise a resin binder component that contains a high molecular weight polymer, e.g. a polymer having an Mw of at least about 40,000 daltons.
