Thermal Cycling of 300 nm Buried Damascene Copper Interconnect Lines by Joule Heating

Read D.T., Geiss R.H., National Institute of Standards and Technology, US

We report tests of 300 nm wide damascene copper interconnect lines in silicon oxide dielectric to failure under high amplitude, low frequency alternating current. The cyclic minimum and maximum resistances were obtained from the measured [...]

Metallic submicron wires and nanolawn for microelectronic packaging. Concept and first evaluation

Fiedler S., Zwanzig M., Schmidt R., Scheel W., Fraunhofer Institut Zuverlässigkeit und Mikrointegration (IZM), Berlin, DE

Starting with a brief review of submicron wire production techniques, promising applications of submicron and nano wires are discussed. Observed attractive properties of metal rod decorated metal surfaces, so called nano lawn, for low energy [...]

Residual Stress Measurements of High Spatial Resolution

Vogel D., Luczak F., Michel B., Fraunhofer Institute for Reliability and Microintegration, DE

Residual stresses in semiconductor and MEMS devices superposing functional and environmental loading are one of the crucial reliability issues as they can add significant stress levels leading finally to component damage. Most of routinely used [...]

Synthesis, Reliability and Applications of Nanocrystalline CVD-grown Diamond and MicroDevice Fabrication

Wiora M., Brühne K., Flöter A.C., Gluche P., Fecht H-J., University of Ulm, DE

The correlation between the micro- and nanostructure of a material and its physical and chemical properties is the key issue in materials development. Considerable progress has been achieved recently by the development of new processing [...]

Improvement of Stab Resistant Body Armor Using SiO2 Nanoparticles Dispersed into Silane Coupling Agent through Sonic Cavitation

Lambert V., Mahfuz H., Bordner P., Florida Atlantic University, US

Enhancing a flexible body armor using the Shear Thickening Fluid theory (STF) with use of SiO2 nanoparticles has shown good results regarding the stab resistance. A completely new approach based on investigations demonstrates that silated [...]

High Strength Metal-Carbon Nanotube Composites

Goyal A., Wiegand D.A., Owens F.J., Iqbal Z., New Jersey Institute of Technology, US

Carbon nanotubes have been extensively investigated for developing polymer matrix nanocomposites and a number of such nanocomposites are already being used in various applications [1, 2]. Metallic composites, particularly those of aluminum, containing carbon nanotubes [...]

Fabrication of Nano-engineered Composites Reinforced with Carbon Nanotubes (CNTs)

Wicks S.S., Yamamoto N., Guzman de Villoria R., Ishiguro K., Cebeci H., Wardle B.L., Massachusetts Institute of Technology, US

Composites, consisting of aligned advanced fibers embedded in epoxy, are common structural materials used in the aerospace industry for their superior strength to weight ratio and their versatility in tailoring specific mechanical properties, among other [...]

Adapting carbon nanotubes for fine composite structures

Shaffer M., Verdejo R., Tran M., Menner A., Bismarck A., Imperial College London, UK

Although encouraging results have been obtained for nanotube-filled polymers, significant improvements over conventional fillers have proved elusive. A critical factor is the reliance on CVD-grown material, which is available in large quantity at reasonable purity, [...]

Halloysite Nanotubes in Polymers

Daly R.C., Fleischer C.A., Wagner A.L., Duffy M., NaturalNano, Inc., US

Halloysite Nanotubes (HNT TM) provide a new avenue for the preparation of nanocomposites. These unique tubes can be dispersed by normal extrusion processes in a variety of polymer melts to produce nanocomposites with unusual physical [...]

Development of nanocomposites with carbon nanotubes in a thermoplastic elastomer matrix

Broza G., Roslaniec Z., Schulte K., Technische Universitaet Hamburg, TUHH, DE

Thermoplastic elastomers (TPEs) have the potential for application as engineering materials because of their novel properties and ease of processing. We have developed a polycondensation process, which allows the manufacturing of polybutylene terephthalate/polyoxytetramethylene (PBT/PTMO) block [...]
