“…1-(4-Ethoxyphenyl)-5-mercapto-1H-tetrazole [37], and Janus Green B [38] can be used as levelers for acid copper plating. BTA can also form an inhibiting film on the copper electrodeposited layer after immersion in BTA solution [39]. Numerous studies were devoted to the interaction of BTA with oxide-free [26,[40][41][42][43][44][45][46][47][48][49][50][51][52] and oxide-covered [28,52] copper surfaces.…”

“…For the determination of the molecular structure and interactions of BTA with the copper surface, a few attempts were carried out using the TOF-SIMS technique [52,[72][73][74][75][76]. Moreover, the interaction of similar compounds with copper was examined by TOF-SIMS [35,39]. However, no trials have been devoted to the analysis of the copper electrodeposition under the static regime of TOF-SIMS that allows for the resolution of the molecular structure of Cu-BTA.…”

Benzotriazole (BTA) is an important compound that demonstrates the strongest anticorrosion properties of copper and plays a role as a leveler and an additive to the electroplating bath for control of the roughness and corrosion resistance of the electrodeposited copper layer. In this paper, we combined cyclic voltammetry (CV), time-of-flight secondary-ion mass spectrometry (TOF-SIMS), surface enhanced Raman spectroscopy (SERS), and atomic force microscopy (AFM) to study the interaction of BTA with copper surfaces at varied concentrations with and without the presence of chloride ions. We identified the most relevant molecular copper and its complex forms with BTA on the copper electrodeposited layer. BTA is adsorbed and incorporated into the copper surface in monomeric, dimeric, trimeric, tetrameric, and pentameric forms, inhibiting the copper electrodeposition. The addition of chloride ions diminishes the inhibiting properties of BTA. The Cu-BTA-Cl complexes were identified in the forms C12H8N6Cu2Cl− and C6H4N3CuCl−. Coadsorption of chloride ions and BTA molecules depends on their concentration and applied potential. Chloride ions are replaced by BTA molecules. BTA and chloride ions, depending on their concentration and applied potential, control the copper nucleation processes at the micro- and nanoscales. We compared the abilities and limitations of TOF-SIMS and SERS for studies of the interactions of benzotriazole with copper and chloride ions at the molecular level.
