Corrosion Inhibition Mechanism and Research Progress of Compounding Corrosion Inhibitors in Cu/Co Barrier Layers
Slurry is a crucial component of chemical mechanical polishing(CMP),with corrosion inhibitors being a fundamental part.Traditional corrosion inhibitors exhibit poor corrosion inhibition and low efficiency.However,compounded corrosion inhibitors have emerged as a focal point in CMP research owing to their high efficiency,superior corrosion inhibition effects,and environmental friendliness.In this study,the mechanism of azole corrosion inhibitors on Cu/Co barrier layers is analyzed,and a summary of the recent five-year research progress on new composite inhibitors in the CMP process globally is presented.Evaluations were conducted using various methods such as electrochemical techniques(EIS,OCP,and Tafel),surface analysis techniques(SEM and AFM),and molecular dynamics simulations(DFT and ReaxFF)to analyze the corrosion inhibition effect of these inhibitors.Finally,the current challenges and prospects of composite corrosion inhibitors are summarized.
