Abstract:
1. A method of forming a patterned material layer on a substrate, the method comprising: providing a substrate having a material layer on a surface thereof; depositing a photoresist composition on the substrate to form a photoresist layer on the material layer; applying a top antireflective/barrier layer material on the photoresist layer, thereby forming a coated substrate, the top antireflective coating and barrier layer material comprising at least one silicon-containing moiety and at least one aqueous base soluble moiety; patternwise exposing the coated substrate to imaging radiation; removing simultaneously the top antireflective/barrier layer material and portions of the photoresist layer from the coated substrate, thereby forming a patterned photoresist layer on the material layer; and transferring the photoresist layer pattern to the material layer.
