A New Copper Electrodeposition Scheme to Reduce Void Defects after Chemical Mechanical Polishing

Lin J.Y., Wang Y.Y., Wan C.C., Wang Y.Y., National Tsing Hua University, TW

Deposition of highly (111) oriented conductive layer is required for achieving better electromigration resistance and lower resistivity. Moreover, the amount of void defects decreases as the (111)/(200) ratio increases in CMP process. Hence, we investigated [...]

Investigation of the Behaviors of Various Electroplated Copper films during CMP

Feng H.P., Cheng M.Y., Wang Y.Y., Wan C.C., Wang Y.Y., National Tsing Hua University, TW

The behaviors of various electroplated copper films during CMP are important for removal mechanism and defect generation. This article was to study the characteristics of various copper films during CMP, including impurity effect and current [...]

Curing Quantum Dots using Inductively Coupled Argon Plasma

Mei T., Nie D., Djie H.S., Ooi B.S., Nanyang Technological University, SG

Great advancement achieved in quantum dot (QD) growth using Molecular Beam Epitaxy or Metal-Organic Vapor Phase Epitaxy (MOVPE) has made QD-based devices demonstrate superior performances.1 However, QD structures are highly-strained material systems grown under low [...]

Cold Cathode Fluorescence Light with Amorphous Diamond Coated Electrodes

Sung J.C., Kan M-C, Kinik Company, TW

Amorphous diamond is the only material that can emit electrons in vacuum when applied with an electrical field of only a few volts per micron and such current can increase hundreds or millions times when [...]

Characterization of Aluminum Nitride Nanostructures by XANES and FTIR Spectroscopies with Synchrotron Radiation

Bellucci S., Balasubramanian C., Cinque G., Marcelli A., Cestelli Guidi M., Piccinini M., Popov A., Soldatov A., Onorato P., INFN-Laboratori Nazionali di Frascati, IT

We investigated nano-systems of AlN synthesized by DC arc-plasma-induced melting of aluminum in a nitrogen–argon ambient. Actually, the reaction of molten Al with N2 gas yields on a water-cooled surface a mixture of both nanowires [...]

The Impact of Nano-Materials on UV-Protective Coatings

Cayton R.H., Sawitowski T., Nanophase Technologies Corporation, US

UV-protective, nanocomposite coatings are made by embedding nanocrystalline zinc oxide particles in a polymer matrix. The benefits accrued by incorporating nanoparticles into a polymer matrix become economically driven when several advantageous properties are obtained simultaneously, [...]

Enhancement of Mechanical Properties and Environmental Resistance of Glass Fibre from Nanocomposite Coating

Gao S.L., Mäder E., Plonka R., Leibniz-Institute of Polymer Research Dresden, DE

The severe surface flaws of brittle materials can be ‘healed’ using coating. Here, we describe an inexpensive and applicable process by which a nanometer-scale polymer coating layer based on styrene butadiene with varied clays and [...]

Conductive Carbon-Nanotube/Polymer Composites: Spectroscopic Monitoring of the Exfoliation Process in Water and the Crucial Role of Wetting

Grossiord N., Loos J., Meuldijk J., Regev O., Miltner H.E., Van Mele B., Koning C.E., Eindhoven University of Technology, NL

For the preparation of conductive polystyrene/SWNT nanocomposites, a recently developed, versatile, latex-based technology is applied. A low molar mass PS fraction, probably acting as a wetting agent for the SWNTs, seems to be required for [...]

New route to manufacture high performance carbon nanotubes nanocomposites based on pre-dispersed concentrates generated by in-situ polymerization

Claes M., Bonduel D., Pegel S., Alexandre M., Poetschke P., Dubois P., Luizi F., Nanocyl SA, BE

We describe here an original method which relies upon the in situ polymerization of olefin catalyzed by a highly active metallocene complex physicochemically anchored onto the carbon nanotube surface. As a result, carbon nanotubes are [...]

Unique Roles of DNA Wrapped SWNTs: In-situ Fabrication of Self-Doped Polyaniline Nanocomposites

Ma Y.F., Ali S.R., He H.X., Rutgers University, US

Inspired by the remarkable electrical conductivity, the superior mechanical properties of carbon nanotubes(CNTs), and the rich optical, electrical and electrochemical properties of conducting polymers, nanocomposites of conducting polymers and CNTs have been pursued with a [...]
