Microstructural Study of the Effect of Chloride Ion on Electroplating of Copper in Cupric Sulfate-Sulfuric Acid Bath
The purpose of this work is to study the electrocrystallization behavior of the copper deposit on pure titanium substrate. The electroplating was conducted at 0.7 A/cm2, 65°C in cupric sulfate-sulfuric acid bath with various chloride additions 45-350 ppm . Initial growth morphology and microstructure of the deposit were examined with a field-emission scanning electron microscope FESEM and a hig...
متن کاملTransient Adsorption of Sulfate Ions during Copper Electrodeposition
Surface-enhanced Raman scattering ~SERS! spectroelectrochemical investigations have been carried out in real time on the electrodeposition of copper from sulfuric acid solutions. Sulfate spectra were observed during copper deposition, but not on a copper surface at the same potential in the absence of copper ions in solution. This indicated that sulfate adsorption is a transient process associa...
متن کاملPulsed Electrodeposition of Copper
Pulsed electrolysis of copper has been systematically investigated by electrodepositing copper from a copper sulfate bath. Pulse duty cycles of 5 to 80 percent, at frequencies from 10 to 100 Hz with current densities ranging from 2.5 to 7.5 A/dm2 were employed. The appearance of Hull Cell panels with both direct current and pulsed current was recorded. The influence of pulsed current on current...
متن کاملEffect of Sodium Dodecyl Sulfate on Copper Anodic Dissolution in Phosphoric Acid Solution
In Electrochemical Mechanical Planarization process (ECMP), concentrated phosphoric acid is usually used as electrolyte. Role of sodium dodecyl sulfate (SDS) in anodic dissolution of Cu in concentrated phosphoric acid was studied by Cyclic Voltammetry (CV), inhibition efficiency (IE) calculation and in-situ observation of the Cu electrode surface at anodic overpotentials. It was found that pres...
متن کاملMagneto-Dendrite Effect: Copper Electrodeposition under High Magnetic Field
Ionic vacancy is a by-product in electrochemical reaction, composed of polarized free space of the order of 0.1 nm with a 1 s lifetime, and playing key roles in nano-electrochemical processes. However, its chemical nature has not yet been clarified. In copper electrodeposition under a high magnetic field of 15 T, using a new electrode system called cyclotron magnetohydrodynamic (MHD) electrode ...
