  • Patent number: 9353339
    Abstract: The present invention proposes a method for removing an oxide formed on the surface of a copper film used in the process of manufacturing a circuit for a semiconductor, an organic light-emitting diode, an LED, or a liquid crystal display without causing corrosion on a lower metal film. The composition including corrosive amine may remove a metal oxide depending on the content of additive ranging from 0.01 to 10% regardless of the content of ultrapure water. A polar solvent other than the corrosive amine may efficiently remove an oxide from the surface of the metal when the same contains water and 0.01 to 20% of the additive.
