The formation of inhibitive benzotriazole films on copper and copper alloyed with silver has been studied with scanning electrochemical
microscopy (SECM) and X-ray photoelectron spectroscopy (XPS). The SECM measurements showed that the film grows
rapidly on oxygen-free dehydrated copper (OF-HC) and that the rate depends on the substrate potential. The benzotriazole films
were also observed on silver alloyed copper; however, electropolishing prevents film growth by enriching the surface with silver.
XPS results show that the film consisted of [Cu(I)–BTA] on both materials. No evidence of [Ag(I)–BTA] was found.
