    摘要: The present invention provides new light absorbing compositions suitable for use as antireflective coating compositions (“ARCs”), including for deep UV applications. The antireflective compositions of the invention are particularly useful where a planarizing coating layer is required. ARCs of the invention contain a low molecular weight resin, a plasticizer compound and/or a low Tg resin. The invention also includes methods for applying forming planarizing ARC coating layers.

    摘要: 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. ARCs of the invention exhibit exceptional conformality upon application to a substrate surface. For example, ARCs of the invention can coat substantial topography such as vertical and sloping steps with high conformality.
