Thermodynamic Properties of Sulfur Hexafluoride

May 1, 2000
Author(s)
John J. Hurly, Dana R. Defibaugh, Michael R. Moldover
We present new vapor phase speed-of-sound data u(P,T), new Burnett density-pressure-temperature data ρ(P,T), and a few vapor pressure measurements for sulfur hexafluoride (SF 6). The speed-of-sound data spanned the temperature range 230 K {less than or

Tomography of Integrated Circuit Interconnect With an Electromigration Void

May 1, 2000
Author(s)
Zachary H. Levine, A R. Kalukin, M Kuhn, S P. Frigo, I McNulty, C C. Retsch, Y Wang, Uwe Arp, Thomas B. Lucatorto, Bruce D. Ravel, Charles S. Tarrio
An integrated circuit interconnect was subject to accelerated-life conditions to induce an electromigration void. The silicon substrate was removed, leaving only the interconnect encased test structure encased in silica. We imaged the sample with 1750 eV

Ultra-Low Resistance Contacts to GaAs/AlGaAs Quantized Hall Resistors

May 1, 2000
Author(s)
Kevin C. Lee
Contacts to quantized Hall resistors (QHRs) must meet demanding specifications for contact resistance, reliability, ruggedness, and resistance to degradation. A study of contact materials showed that contacts composed primarily of Indium meet all of these

UV Light From the Ground Term of Ti-Like Ytterbium, Tungsten, and Bismuth

May 1, 2000
Author(s)
James V. Porto, John D. Gillaspy
We have used an electron beam ion trap (EBIT) to measure the wavelength of the J=2 to j=3 magnetic dipole transition in the 3d 4 ground term of Ti-like Ytterbium and Tungsten. These results extend the range of measurements of this line along the

Vectorial second-harmonic magneto-optic kerr effect measurement

May 1, 2000
Author(s)
Pavel Kabos, Anthony B. Kos, Thomas J. Silva
A significant modification of an existing experimental technique based on the second-harmonic magneto-optical Kerr effect (SH-MOKE) is introduced. With a p-polarized pumping optical wave incident upon a magnetic film, the transverse component of

An Automated Hierarchical Process Planning System

April 28, 2000
Author(s)
Thomas R. Kramer, Hui-Min Huang, Elena R. Messina, Frederick M. Proctor, Harry A. Scott
This paper describes an automated hierarchical process planning system for machining and inspecting discrete parts in an RCS type control system. The system integrates planning with control of a 3-axis machining center and a coordinate measuring machine

Interfacial Response of a Fluorescent Dye Grafted to Glass

April 12, 2000
Author(s)
Joy P. Dunkers, Jospeh L. Lenahrt, J Van Zanten, Richard~undefined~undefined~undefined~undefined~undefined Parnas
The properties of an epoxy/glass interfacial region are studied by covalently grafting a fluorescent probe to the glass surface. A dimethylaminonitrostilbene fluorophore is tethered to a triethoxysilane-coupling agent, generating a fluorescently labeled

Full-Scale House Fire Experiment for InterFIRE VR, May 6, 1998. Report of Test.

April 10, 2000
Author(s)
Anthony D. Putorti Jr., Jay A. McElroy
A public/private partnership involving multiple federal agencies and private industry was assembled to develop a comprehensive fire investigation training tool. The partnership consisted of the following federal agencies: the Bureau of Alcohol, Tobacco and
