ABSTRACT:
This invention relates to antireflective coatings comprising polymeric polyoxyalkylenated colorants. More particularly, the present invention relates to antireflective coatings for utilization in forming thin layers between reflective substrates and photoresist coatings. Such antireflective coatings are very useful and beneficial within the production and fabrication of semiconductors through photolithographic procedures due to the liquid, non-crystallizing nature of polyoxyalkylenated colorants, and the lack of potentially damaging counterions, metals, and/or electrolytes within the inventive antireflective colored coatings. The inventive coatings may also be applied on lenses, mirrors, and other optical components. Methods of forming such antireflective coatings are also contemplated within this invention.
