  • Patent number: 6908892
    Abstract: The present invention is a photoresist remover composition used in order to remove photoresist during the manufacturing process of semiconductor devices, such as large-scale integrated circuits and very large-scale integrated circuits. The present invention comprises 2˜20 weight % of water-soluble hydroxylamine, 5˜15 weight % of oxime compound containing 2 or 3 hydroxyl groups, and 30˜55 weight % of alkyl amide. The photoresist remover composition according to the present invention can easily and quickly remove a photoresist layer that is cured by the processes of hard-bake, dry-etching, and ashing and a side-wall photoresist polymer that is produced from the lower metal film by the reaction of the photoresist with etching and ashing gases during these processes. Especially, the photoresist remover composition has a good property of removing the side-wall photoresist polymer produced from the layers of aluminum, aluminum alloy, and titanium nitride.
