| titleOfInvention | Etching solution capable of effectively reducing galvanic effect |
| abstract | The present invention is to provide an etching solution capable of effectively reducing Galvanic effect, wherein the etching solution is obtained by way of dissolving an etchant and a nitrogen containing five-member heterocyclic compound in water. Thus, when at least one first metal (e.g., gold) and at least one second metal (e.g., copper) disposed on a substrate is treated with a wet etching process by using this etching solution, the nitrogen containing five-member heterocyclic compound would form an organic protecting film on the first metal having higher reduction potential, so as to effectively avoid the second metal from being over etched resulted from the Galvanic effect. |
