Electrodeposition of Aluminum-Transition Metal Alloys from Chloroaluminate Ionic Liquids

September 13, 2010
Author(s)
Gery R. Stafford, Hussey Charles
… molten salts, which consist of inorganic or organic chloride salts combined with anhydrous aluminum chloride. One of the attributes of the chloroaluminates is … transition metals, either in the form of discrete anionic chloride complexes (basic melt) or metal ions that are weakly …

Bottom-up Copper Filling of Millimeter Size Through Silicon Vias

January 12, 2019
Author(s)
Daniel Josell, Thomas P. Moffat, Lyle Menk, Andrew Hollowell, M Blain
… using a combination of a polyoxamine suppressor and chloride, analogous to previous work filling TSV that were an order of magnitude smaller in size. For high chloride concentration (i.e., 1 mmol/L) bottom-up deposition … section at the bottom. In contrast, deposition from low chloride electrolytes, proceeds with a passive-active …

Microstructure and Texture in Copper Filled Millimeter Scale Through Silicon Vias

March 17, 2022
Author(s)
Daniel Josell, Trevor Braun, Thomas P. Moffat
… filling evolution it records, changes substantially with chloride concentration for the concentrations of polymer suppressor used. With chloride concentrations of 80 μmol∙L-1 and less, elongated … angled upward from the sidewalls toward the center of the v-shaped growth front. In a limited region adjacent to the …

The Electrodeposition of Al-Cu Alloys from Room-Temperature Chloroaluminate Electrolytes

October 1, 1999
Author(s)
Gery R. Stafford, V D. Jovic, Thomas P. Moffat
… of Al onto Cu(lll), were investigated in acidic aluminum chloride/1-methyl-3-ethylimidazolium chloride ambient … Al codeposition was found to occur at approximately 0.30 V versus the Al(III)/Al couple, and the Cu-Al alloy … reaching a maximum value of 43% atomic fraction Al at 0 V. Alloy deposition potentials based on free energy …

Influence of Silica Fume on Diffusivity in Cement-Based Materials. I. Experimental and Computer Modeling Studies on Cement Pastes

June 1, 2000
Author(s)
Dale P. Bentz, O M. Jensen, A M. Coats, Frederik P. Glasser
… its resistance to diffusion of both tritiated water and chloride ions. Because the pores in the C-S-H are extremely … the diffusivity of the gel is about a factor of five. For chloride ions, when a diffusivity value 25 times lower than … excellent agreement is obtained between experimental chloride ion diffusivity data and results generated based on …

Recombinant Anthranilate Synthase From the Marine Hyperthermophile Archaeoglobus Fulgidus: Expression, Purification, Characterization and Stabilization of the Cooperatively-Regulated Heterotetrameric Enzyme
