    • 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.
