    • PURPOSE: Provided is an organic anti-reflection coating composition, which decreases an adverse effect of reflection from a background substrate in a photolithography process using various radiations, gives excellent resolution and has no loss in thickness by the photoresist solvent. CONSTITUTION: The organic anti-reflection coating composition for an ArF photoresist is characterized by comprising the compound of the formula 1 as a light absorbing agent, wherein each R is independently or simultaneously hydrogen, hydroxy, halogen, nitro group, amino group, a C1-C8 alkyl group optionally containing a hydroxy group, a C1-C8 alkoxy group optionally containing a carbonyl group, benzene, a C5-C6 cycloalkyl group, an arylalkyl group, or an alkylaryl group, provided that at least one of them is not a hydrogen.
    • 目的:提供一种有机防反射涂料组合物,其在使用各种辐射的光刻工艺中减少来自背景基板的反射的不利影响,提供优异的分辨率并且通过光致抗蚀剂溶剂不会损失厚度。 构成:用于ArF光致抗蚀剂的有机防反射涂料组合物的特征在于包含式1的化合物作为光吸收剂,其中每个R独立地或同时是氢,羟基,卤素,硝基,氨基,C1 任选含有羟基的C 1-8烷基,任选含有羰基的C 1 -C 8烷氧基,苯,C 5 -C 6环烷基,芳烷基或烷芳基,条件是它们中的至少一个不是 氢。
