  • Publication number: 20060177761
    Abstract: The present invention relates to a thinner composition for removing resist used in TFT-LCD manufacturing processes, and more particularly to a thinner composition for removing resist that comprises: a) 0.1 to 5 wt % of an inorganic alkali compound; b) 0.1 to 5 wt % ofan organic amine; c) 0.1 to 30 wt % of an organic solvent; d) 0.01 to 5 wt % of a surfactant comprising an ionic surfactant and a non-ionic surfaciant in the weight ration of 1:5 to 1:25; and e) 60 to 99 wt % of water. The thinner composition for removing resist of the present invention has good efficiency of removing unwanted resist film constituents formed on the edge of the resist film or at the back of the substrate in TFR-LCD device and semiconductor device manufacturing processes. Also, it does not have the problem of equipment corrosion.
