| titleOfInvention | Etchant for izo layer and etching method thereof |
| abstract | An IZO membrane etching solution including an oxalic acid series, a phosphate series compound, a hydrocarbon series compound, and deionized water is provided. Preferably, from 2 to 8% by weight of the oxalic acid series based on the total weight of the composition; 0.5 to 4% by weight of a phosphate compound; 0.0005 to 0.05% by weight of a hydrocarbon-based compound; And it provides an IZO membrane etching solution comprising deionized water so that the total weight of the composition is 100% by weight. This etching solution has the advantage of reducing the attack of the photoreactive material during the etching process, leaving no residue after etching.n n n In addition, by using the etching solution according to the present invention it is possible to improve the oxalic acid crystallization phenomenon below 0 degrees, which is known as a problem of the conventional IZO etching solution, so that crystals do not precipitate at about -5. Therefore, in the manufacturing process of the display apparatus using an IZO film | membrane, there exists an effect which can improve productivity. |
