SUMMARY
Etching aluminum oxide (Al2O3) without affecting aluminum is feasible using specific chemical agents. The discussion highlights the potential use of chelating agents like EDTA, which can selectively dissolve aluminum oxide while preserving aluminum structures. This technique is particularly relevant for microelectronic applications where maintaining aluminum integrity is crucial. The consensus confirms that careful selection of etching agents is essential for successful outcomes.
