Abstract
Corrosion resistance of electrochemical copper coat ing realized in the presence of essential oils
Author(s): K. Dahmani 1 , M. Galai 1* , A. Elhasnaoui 3 , B.Temmar 2 , A. El Hessni 3 and M. Cherkaoui 1Copper coating was developed electrolytically on in terconnections in technology used in wafer level pa ckaging. These coatings are adherent and uniforms, the depos ition rate reached 23 μ m/h. The quality of the depo sits was improved by the addition of a cinnamon extract in t he plating bath. The morphology of the coatings was evaluated by scanning electron microscopy. The anti-corrosion properties of copper coatings in the absence and p resence of different cinnamon extract concentrations were stud ied in a 3% NaCl solution using the potentiodynamic polarization, electrochemical impedance spectroscop y (EIS) and scanning electron microscope (SEM). The result showed that the presence of 150 ppm cinnamon improv es the corrosion resistance of the copper substrate
