ABSTRACT:
The invention provides new light absorbing crosslinking compositions suitable for use as an antireflective composition, particularly for deep UV applications. The antireflective compositions of the invention comprise a photoacid generator that is activated during exposure of an overcoated photoresist. Antireflective compositions of the invention can significantly reduce undesired footing of an overcoated resist relief image.
