摘要: A deep ultraviolet absorbent comprising at least one compound having one or more glycidyl groups in the molecule and at least one anthracene derivative, and a solvent capable of dissolving these compounds is effective for preventing reflection of deep ultraviolet light from a substrate during formation of resist pattern, resulting in forming ultra-fine patterns without causing notching and halation.

摘要: An anthracene derivative having at least two groups of the formula:
wherein R¹ and R² are independently hydrogen, alkyl, alkoxy, etc., is particular effective for forming an antireflection coating for preventing multiple reflection of exposing light from a highly reflective substrate, etc.摘要翻译: 具有至少两个下式的蒽衍生物:其中R 1和R 2独立地为氢,烷基,烷氧基等,其特征在于形成用于防止多次反射曝光的抗反射涂层 来自高反射性基板的光等
