NEGATIVE-WORKING PHOTOIMABEABLE BOTTOM ANTIREFLECTIVE COATING

摘要

The present invention relates to novel negative−working, photoimageable, and aqueous developable antireflective coating compositions and their use in image processing by forming a thin layer of the novel antireflective coating composition between a reflective substrate and a photoresist coating. The negative bottom photoimageable antireflective coating composition is capable of being developed in an alkaline developer and is coated below a negative photoresist.
