摘要:
A composition for removing a photoresist, the composition including about 1% by weight to about 10% by weight of tetramethyl ammonium hydroxide (“TMAH”), about 1% by weight to about 10% by weight of an alkanol amine, about 50% by weight to about 70% by weight of a glycol ether compound, about 0.01% by weight to about 1% by weight of a triazole compound, about 20% by weight to about 40% by weight of a polar solvent, and water, each based on a total weight of the composition.
