Abstract

A corrosion resistant agent and stripping agent composition disclosed by the present invention comprises: 1-10% by weight of organic ammonium hydroxide season, 40-80% by weight of dimethylsulfoxide, 1-25% by weight of organic solvent based on glycol ether, 1-25% by weight of alkylamine possessing 1-20 carbon atoms; 0.001-1% by weight of inorganic base or salt thereof; and the balance water. According to the corrosion resistant agent and stripping agent composition containing the above components, a colored filter corrosion resistant agent can be removed from a substrate by dissolution, so that a best stripping capability can be obtained, the colored filter plugging in a device can be reduced to the minimum level, a negative organic insulating film corrosion resistant agent, a positive organic insulating film corrosion resistant agent and the colored filter corrosion resistant agent can be stripped, and a bottom layer and various metal wirings are not damaged.

Description

technical field [0001] The present invention relates to a resist stripper composition. Background technique [0002] The color filter may be installed in a color imaging device having an image sensor such as a complementary metal oxide semiconductor (CMOS) or a charge coupled device (CCD) and actually used to generate a color image. In addition, color filters are widely used in applications of imaging devices such as plasma display panels (PDPs), liquid crystal displays (LCDs), field emission displays (FELs), light emitting devices (LEDs), and these application fields are rapidly expanding these days range. In particular, as the use of LCDs has been increasing in recent years, color filters are considered to be one of the most important devices in reproducing the color tone of LCDs. [0003] The color filter substrate includes: a black matrix that functions to shield light leakage between the red (R), green (G) and blue (B) patterns and each pixel while improving the dista...
