| titleOfInvention | Etchant composition of organic light emitting diode display |
| abstract | The present invention relates to a pharmaceutical composition comprising 0.1 to 34% by weight ammonium peroxodisulfate ((NH 4 ) 2 S 2 O 8 ); 0.1 to 9% by weight of a nitric acid compound; 0.1 to 10% by weight of an acetic acid-based compound; 0.2 to 5% by weight of a fluoride-based compound; 0.01 to 3% by weight of a boron compound; And 39 to 73% by weight of water, but does not comprise an azole-based compound.n n n Since the etching solution composition of the present invention does not contain hydrogen peroxide, stability and process margin can be ensured, and an excellent taper etching profile can be obtained.n n n n Ammonium peroxodisulfate, etchant, aluminum |
