    • PURPOSE: Provided is an organic anti-reflection coating composition which forms an under coating to decrease an adverse effect of reflection from a background substrate in a photolithography process using various radiations. 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 X is a hydrogen atom or methyl; and at least one of R1-R15 is hydroxy group and the others are independently or simultaneously hydrogen, halogen, nitro group, amino group, a C1-C3 alkyl group optionally having a hydroxy group, a C1-C3 alkoxy group optionally having a carbonyl group, benzene, or a C5-C6 cycloalkyl group.
    • 目的:提供一种有机抗反射涂层组合物,其在使用各种辐射的光刻工艺中形成底涂层以减少来自背景基板的反射的不利影响。 构成:用于ArF光致抗蚀剂的有机抗反射涂层组合物的特征在于包含式1的化合物作为光吸收剂,其中X是氢原子或甲基; 并且R 1 -R 5中的至少一个为羟基,其余为氢,卤素,硝基,氨基,任选具有羟基的C1-C3烷基,任选具有羰基的C1-C3烷氧基 基团,苯或C5-C6环烷基。
