    • PURPOSE: A photo-resist stripping composition is provided to prevent the occurrence of corrosion with respect to metal wirings under a photo-resist film in a stripping process and a deionized water-based rinsing process. CONSTITUTION: A photo-resist stripping composition includes 0.5 to 5 weight% of alkylammonium hydroxide, 60-90 weight% of an aprotic polar solvent, 0.1-3 weight% of aromatic polyalcohol, 0.1-5 weight% of linear polyalcohol, and 5-30 weight% of water. The aromatic alcohol includes one or more carboxylic groups or alkylester groups and includes three or more hydroxylic groups. The aromatic polyalcohol is selected from a group including gallic acid, methyl gallate, ethyl gallate, propyl gallate, butyl gallate, and the mixture of the same. The linear polyalcohol includes three or more hydroxyl groups. The alkylammonium hydroxide is selected from a group including tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, and the mixture of the same.
    • 目的:提供光阻剥离组合物,以防止在剥离过程和去离子水基漂洗工艺中在光致抗蚀剂膜下相对于金属布线发生腐蚀。 构成:光阻剥离组合物包含0.5-5重量%的烷基氢氧化铵,60-90重量%的非质子极性溶剂,0.1-3重量%的芳族多元醇,0.1-5重量%的线性多元醇和5- 30重量%的水。 芳族醇包括一个或多个羧基或烷基酯基,并且包括三个或更多个羟基。 芳族多元醇选自不含有没食子酸,没食子酸甲酯,没食子酸乙酯,没食子酸丙酯,没食子酸丁酯及其混合物的组。 线性多元醇包括三个或更多个羟基。 烷基氢氧化铵选自氢氧化四甲基铵,氢氧化四乙铵,氢氧化四丙基铵及其混合物。
