    • PURPOSE: Provided is a solvent composition for removing photoresist used in patterning copper film for electronic circuit or display device having excellent removal of the photoresist remained on top portion of the patterned copper film. CONSTITUTION: The solvent composition comprises 10-30wt.% of at least one selected from N-methylethanolamine, diethylethanolamine and dimethylethanolamine; 10-80wt.% of glycol ether solvent; 9.5-50wt.% of polar solvent; and 0.5-10wt.% of corrosion-resistant agent. The photoresist film(40) is formed by vapor-depositing copper on substrate(10) to form a first metallic layer(11) and coating the photoresist on top portion of the first metallic layer(11). On top side of the photoresist film(40), mask(M) having permeable part(E) to pass light through and shield part(F) to block light is formed. After then, high energy activation ray radiates over top portion of the mask(M) to expose the photoresist film(40)match with the permeable part(E). After completing the exposure, the photoresist film is under development, thereby obtaining the pattern of copper film.
    • 目的:提供一种用于去除用于电子电路的铜膜图案的显影剂的溶剂组合物或具有优异去除残留在图案化铜膜的顶部上的光致抗蚀剂的显示装置。 构成:溶剂组合物包含10-30重量%的选自N-甲基乙醇胺,二乙基乙醇胺和二甲基乙醇胺中的至少一种; 乙二醇醚溶剂10-80wt%; 9.5-50重量%极性溶剂; 和0.5-10重量%的耐腐蚀剂。 光致抗蚀剂膜(40)通过在基板(10)上气相沉积铜形成第一金属层(11)并在第一金属层(11)的顶部上涂覆光致抗蚀剂而形成。 在光致抗蚀剂膜(40)的顶侧,形成具有使光通过的屏蔽部(E)的透光部(E)和屏蔽部(F)遮挡光的掩模(M)。 之后,高能激活光线辐射在掩模(M)的顶部上,以使光致抗蚀剂膜(40)与可渗透部分(E)相匹配。 曝光完成后,光致抗蚀剂膜正在显影中,从而获得铜膜图案。
