International Business Machines Corporation, Steven Capella, May 4, 2004: US06730454 (50 worldwide citation)

Antireflective compositions characterized by the presence of an SiO-containing polymer having chromophore moieties and transparent moieties are useful antireflective hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity prope ...
