As the miniaturization trend in integrated circuits fabrication continues, alternative liner materials in copper interconnects have been actively explored. Cobalt has been widely investigated and employed due to its low resistance at nanoscales, integration compatibility, as well as benefit of improving copper electromigration resistance. However, direct electrodeposition of copper onto cobalt remains less explored due to the stability issue of cobalt in acidic copper damascene process. Subsequent processes of copper seeding and copper electroplating face increasing technical difficulties when

In the purification process of zinc hydrometallurgy, the spectra of copper and cobalt seriously overlap in the whole band and are interfered with by the spectra of zinc and nickel, which seriously affects the detection results of copper and cobalt in zinc solutions. Aiming to address the problems of low resolution, serious overlap, and narrow characteristic wavelengths, a novel spectrophotometric method for the robust detection of trace copper and cobalt is proposed. First, the Haar, Db4, Coif3, and Sym3 wavelets are used to carry out the second-order continuous wavelet transform on the spectr

An industrial converter slag was treated by a selective reduction-roasting process to recovery cobalt and copper in this study. To maximizing the recovery of cobalt and copper, the major process parameters such as reducing agent, curing agent and roasting temperature were investigated. Under the determined conditions, 95% cobalt and 96% copper can be recovered. According to the mineralogical analysis, it is found that cobalt in the converter slag mainly distributes in the iron-bearing minerals, which migrates with iron during the reduction-roasting process.

Comprehensive research on a high magnetic field’s effect on diffusion is lacking; hence, this study investigates the effect of the magnetization of such a field on diffusion using a copper/cobalt diffusion couple in the diamagnetic/ferromagnetic states, respectively.

The diffusion couple annealed within a temperature range of 1165–1265 K under a 0–6-T high magnetic field. The angle between the diffusion and magnetic field directions was set as 0° and then 180°.

A simulation is a computer program that helps in creating a real time abstract model of a process. Using simulations the costs of conducting experiments have come down and this has achieved flexibility in terms of optimizing parameters and durations. Electrodeposition is a process that uses electrical current to reduce dissolved metal cations from anode so that they form a metal coating on cathode.

The work included measurements of free corrosion potentials, and mass loss in presence and absence of cavitation. The cavitation tests were made at a frequency of 20 KHz and at temperatures of 25°C. Cavitation conditions caused a noble shift in the free corrosion potential for carbon steel and an active one for Cu-Ni 70-30 and cobalt-based alloys.

Abstract Pitting potentials and cyclic potentiodynamic polarization behavior has been determined in sodium chloride solution for a number of stainless steels and other iron, nickel, cobalt and copper based alloys. The predicted corrosion behavior was then compared with the known long term behavior of specimens cut from the same sheet. In general agreement was good except for AL6X and Inconel 718. AL6X would have been predicted to be inert, but specimens from the same sheet suffered crevice corrosion during long term exposures. Inconel 718 would also have been predicted to be highly resistant t

Abstract Time-of-Flight Secondary Ion Mass Spectroscopy TOFSIMS was used to identify the different fragmented species associated with the adsorption of a triazole based inhibitor on alloyed thin films. Copper, cobalt-iron, nickel-manganese, and nickel-iron alloyed films were immersed in an inhibited aqueous solution. Inspection of the positive and negative spectra indicated different fragmented complexes of the inhibitor. In some cases the primary metal of the alloy was where the inhibitor fragments adsorbed thus excluding or lightly covering the secondary alloy. In many cases there are differ

As we move away from a fossil fuel-driven economy, the demand for metals used in energy-dense, rechargeable batteries is increasing; these include cobalt and lithium. Although cobalt is mostly obtained as a by-product from nickel and copper mining, significant amounts also occur in volcanogenic massive sulfide (VMS) deposits, of which Canada has many. However, the primary controls on cobalt distribution in VMS deposits are poorly understood, and may be affected by deformation and metamorphism. We show that cobalt can occur in pyrite, which retains its primary composition through greenschist fa

This Working Paper explores the multifaceted Chinese engagement in the Democratic Republic of the Congo's (DRC) copper and cobalt mining sector. We identified two distinctive approaches for such engagement: one led by central state-owned enterprises (CSOEs) and state-backed policy financial institutions (S-PFIs), and the other by a mix of public and private Chinese companies. The paper argues that while the former approach is embedded with a developmentalist ideology by aiming to utilise resource income to promote infrastructure development, the latter follows a typical extractivist logic of p

The Geo-mapping for Energy and Minerals (GEM) and Targeted Geoscience Initiative (TGI) programs conducted extensive collaborative research on mineral systems with iron oxide-copper-gold (IOCG) and affiliated deposits in prospective settings of Canada. Regional alteration mapping as well as geochemical and geophysical modelling undertaken under the GEM program documented the evolution of polymetallic metasomatic systems with iron-oxide and alkali-calcic alteration and led to an increased recognition of the mineral potential of poorly explored areas and historic deposits of the Great Bear magmat
