Abstract (en)

[origin: WO9219792A1] An etching solution for removing a metallic layer from a substrate contains a hydrogenated compound that dissolves the metal itself while evolving hydrogen and a nitro-substituted organic compound. The solution is characterized by the fact that the selected nitro-substituted organic compound is a compound having an easily hydrogenizable nitro group.
