Abstract:
Co6Al2oxide was prepared using the hydrotalcite route. The obtained solid was thermally stabilized at 500°C and then impregnated with 5 wt.% copper or 1 wt.% ruthenium nitrate solution followed by calcination at 500°C under an air flow. X-ray diffraction results showed that the calcination of the impregnated solids led to the formation of various oxides (CuO, RuO2, Co3O4, CoAl2O4, CoAl2O4). The different impregnated and non impregnated solids were tested in the methane steam reforming reaction (MSR). Methane conversion did not exceed 5% at 800°C in the case of the non impregnated solid, wherea

Abstract:
Based on the redox principle of galvanic displacement reaction, active metal foils, including magnesium (Mg), aluminum (Al) and cobalt (Co), were creatively introduced as new heterogeneous reducing media and were successfully employed in the presence of sonomechanical assistance to produce metallic nanoparticles such as silver, copper, tin and metal oxides such as those of iron, cobalt and ruthenium. Various combinations were investigated to determine the optimum ion/foil pairings for dense and monodisperse colloids. A wide range of nanoscale metallic species can be achieved by this method giv

Abstract:
The dynamic nature of surfaces and interfaces in catalytic oxides, and in metal particle catalysts on oxide supports, is of fundamental importance in heterogeneous catalysis. In-situ electron microscopy with a controlled environment has been used, together with other EM-based techniques, to obtain a better understanding of disorder under reaction conditions in these non-stoichiometric materials. It is important to recognize that the structure of the solid surface under reaction conditions may differ from that occurring under static conditions or in different atmospheres, including the usual EM

Abstract:
Approximately 20% of the processing steps in integrated circuit (IC) fabrication involve surface cleaning and removal of photoresist and plasma etch residues. Continuous device minimization requires the use of thin films (<20 nm), closely spaced features, and ultra shallow junctions (<50nm); as a result, the challenges associated with effective surface cleaning are intensified. In addition, to insure high device performance, incorporation of alternate materials such as copper, ruthenium, and molybdenum, porous low dielectric constant SiO2-based insulators, and hafnium or zirconium oxides

Abstract:
Copper (Cu) electrodeposition on ruthenium (Ru) oxides was studied due to important implications in semiconductor industry. Ruthenium, proposed as the copper diffusion barrier/liner material, has higher oxygen affinity to form different oxides. Three different oxides (the native oxide, reversible oxide, and irreversible oxide) were studied. Native oxide can be formed on exposing Ru in atmosphere. The reversible and irreversible oxides can be formed by applying electrochemical potential. Investigation of Cu under potential deposition on these oxides indicates the similarity between native and r

Abstract:
Ruthenium, proposed as a new candidate of diffusion barrier, has three different kinds of oxides, which are native oxide, electrochemical reversible oxide and electrochemical irreversible oxide. Native oxide was formed by naturally exposed to air. Electrochemical reversible oxide was formed at lower anodic potential region, and irreversible oxides were formed at higher anodic potential region. In this study, we were focusing on the effect of copper electrodeposition on each type of oxides.

As a very promising material of copper diffusion barrier for next generation microelectronics, Ru has already obtained a considerable attention recently. In this dissertation, we investigated ruthenium and ruthenium oxide electrochemical properties and the application as a copper diffusion barrier. Cu under potential deposition (UPD) on the RuOx formed electrochemically was first observed. Strong binding interaction, manifesting by the observed Cu UPD process, exists between Cu and Ru as well as its conductive ruthenium oxide. Since UPD can be conformally formed on the electrode surface, whic

Abstract:
Atomic layer deposition (ALD) of copper films is getting enormous interest. Ultrathin Cu films are applied as the seed layer for electrochemical deposition (ECD) of copper in interconnect circuits and as the non-magnetic material for the realization of giant magnetoresistance (GMR) sensors. Particularly, Co/Cu multi-layered structures require sub 4.0 nm copper film thickness for obtaining strong GMR effects. The physical vapor deposition process for the deposition of the copper seed layers are prone to non-conformal coating and poor step coverage on side-walls and bottoms of trenches and vias,

Besides epoxidation, other reactions that compete with epoxidation were also studied such as formations of allyl-radical, acrolein, acetone on chlorinated Cu2O(001) and formations of propionaldehyde, allyl-radical and acetone on chlorinated RuO2(110) surface.
