Abstract:
1. A method of forming a patterned material feature, comprising: (a) applying a photoresist formulation over a material on a substrate, said photoresist formulation comprising: after (a), (b) said photoresist formulation separating to form a top anti-reflective coating and a photoresist layer, said photoresist layer between said anti-reflective coating and said substrate; after (b), (c) patternwise exposing said photoresist layer to actinic radiation thereby creating a pattern of radiation-exposed regions in said photoresist layer; after (c), (d) selectively removing said antireflective coating and said radiation-exposed regions in said photoresist layer to form openings through said photoresist layer; and after (d), (e) etching or ion implanting through said openings to form said patterned material features.
