Patent ID: 8354365

Claim:
A cleaning liquid for lithography comprising a quaternary ammonium hydroxide in an amount from 5% to 10% by mass, a water-soluble organic solvent in an amount from 35% to 80% by mass, water and an inorganic base, wherein: the quaternary ammonium hydroxide is at least one selected from the group consisting of tetramethyl ammonium hydroxide and tetraethyl ammonium hydroxide; the water soluble organic solvent comprises a highly polar solvent in an amount from 5% to 60% by mass having a dipole moment of no less than 3.0 D, a glycol ether solvent in an amount from 5% to 55% by mass and a polyhydric alcohol in an amount from 5% to 30% by mass; and the total content of the highly polar solvent and the glycol ether solvent is no less than 30% by mass relative to the total mass of the cleaning liquid for lithography; the highly polar solvent is at least one selected from the group consisting of dimethylsulfoxide, N,N-dimethylformamide, N-methylpyrrolidone and γ-buyrolactone; the glycol ether solvent is at least one selected from the group consisting of diethylene glycol monomethyl ether, diethylene glycol monoethyl ether and diethylene glycol monobutyl ether; and the polyhydric alcohol is at least one selected from the group consisting of ethylene glycol, propylene glycol and glycerin.
