IEEE TC-10: What's It All About?

May 1, 2003
Author(s)
Thomas E. Linnenbrink, W. B. Boyer, Nicholas Paulter, S. J. Tilden
The IEEE TC-10 comprises three working groups that have or are generating standards related to the measurement of signals. One of these groups has recently completed the IEEE Std. 1241, "Standard for Terminology and Test Methods for Analog-to-Digital

Implementation of a Reference Measurement System Using CD-AFM

May 1, 2003
Author(s)
Ronald G. Dixson, Theodore V. Vorburger, Angela Guerry, Marylyn H. Bennett, B Bunday
International SEMATECH (ISMT) and the National Institute of Standards and Technology (NIST) are working together to improve the traceability of atomic force microscope (AFM) dimensional metrology in semiconductor manufacturing. The rapid pace of

Influence of Cross-link Density on the Thermal Properties of Thin Polymer Network Films

May 1, 2003
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Wen-Li Wu
Cross-linked epoxy network films were cast onto silicon wafers with a variety of surface treatments. X-ray reflectivity was used to characterize their electron density and thermal expansion in the rubbery state. A transition from bulk to confined expansion

Intermixing of Aluminum-Magnetic Transition Metals Bilayers

May 1, 2003
Author(s)
J D. Buchanan, T P. Hase, B K. Tanner, P J. Chen, L Gan, Cedric J. Powell, William F. Egelhoff Jr.
Grazing incidence x-ray scattering has been used to study interfacial intermixing in thin films of aluminum/transition metal bilayers grown by dc magnetron sputter deposition at room temperature. As with all transition metals, the ferromagnets Fe, Co and

Introducing Material Dispersion in ADI-FDTD

May 1, 2003
Author(s)
Shawn W. Staker, Christopher L. Holloway, Melinda Piket-May
This paper presents the incorporation of material dispersion into ADI-FDTD, ADI-FDTD is an uncontionally stable mathod, allowing the time step to be increased beyond the CFL bound. ADI class problems result in a reduced execution time, while maintaining

Ion Optical Clocks and Quantum Information Processing

May 1, 2003
Author(s)
David J. Wineland, James C. Bergquist, Till P. Rosenband, Piet Schmidt, Wayne M. Itano, John J. Bollinger, Dietrich G. Leibfried, W Oskay
We summarize experiments at NIST that (1) use guantum gates to entabgle ions and thereby improve the measurement signal-to-noise ratio in spectroscopy and (2) implement sympathetic cooling and quantum state transfer techniques, which might be used to

Luminance probes for contrast measurements in medical displays

May 1, 2003
Author(s)
Aldo Badano, Scott Pappada, Edward F. Kelley, Michael J. Flynn, Sandrine Martin, Jerzy Kanicki
We report on a comparative study that examines four conic luminance probes in their ability to measure small-spot display contrast. We performed linear scans of a slit using a computer-controlled stage. We found that, although the probes were assembled

Magnetic and Structural Characterization and Ferromagnetic Resonance Study of Thin Film HITPERM Soft Magnetic Materials for Data Storage Applications

May 1, 2003
Author(s)
Hideyuki Okumura, D J. Twisselmann, Robert McMichael, M Q. Huang, Y N. Hsu, D E. Laughlin, M E. McHenry
HITPERM/SiO 2 single and multilayer thin films have been produced using a target composition of (Fe 70Co 30) 88}Zr 7}B 4}Cu 1}. The as-deposited HITPERM film contains small bcc (or B2) nanocrystals of volume fraction less than 10% surrounded by an

Manufacturing Interoperability

May 1, 2003
Author(s)
Steven R. Ray, Albert T. Jones
As manufacturing and commerce become ever more global in nature, companies are increasingly dependent upon the efficient and effective exchange of information with their partners, wherever they may be. Leading manufacturers rely upon computers to perform

Measurements of the Infrared Absorption Cross-Sections of Haloalkanes and Their Use in a Simplified Calculational Approach for Estimating Direct Global Warming Potentials

May 1, 2003
Author(s)
Vladimir L. Orkin, A G. Guschin, I K. Larin, Robert E. Huie, Michael J. Kurylo III
The infrared absorption cross-sections and integrated band intensities for 21 haloakanes: CFCl 3, CF 2Cl 2, CF 2Br 2, CH 2F 2, CHR 2Cl, CHF 2Br, CF 3Br, CHCl 2-CF 2Cl, CHFCl-CFCl 2, CHCl 2-CF 3, CHClBr-Cf 3, CHFCl-CFd2^Cl, CHFBr-CF 3, CHF 2-CF 3, CH 2Br-CF

Metrics and Metrology for FPDs

May 1, 2003
Author(s)
Edward F. Kelley
We review various methods for making optical measurements of flat panel displays (FPDs). In particular, the measurements outlined in the VESA FPDM2 will be featured. Special attention is given to difficulties in implementing the methods.

Microscopic Structure of a Vortex Line in a Dilute Superfluid Fermi Gas

May 1, 2003
Author(s)
N Nygaard, G M. Bruun, Charles W. Clark, D L. Feder
The microscopic properties of a single vortex in a dilute superfluid Fermi gas at zero temperature are examined within the framework of self-consistent Bogoliubov-de Gennes theory. Using only physical parameters as inputwe study the pair potential, the

Modeling Superconformal Electrodeposition Using the Level Set Method

May 1, 2003
Author(s)
Daniel Wheeler, Daniel Josell, Thomas P. Moffat
Superconformal filling (superfill) occurs when a high aspect ratio feature on a silicon wafer fills due to preferential metal deposition on the bottom surface that permits it to escape before deposition on the side walls causes them to close off. This

Near the Static Fatigue Limit in Glass

May 1, 2003
Author(s)
Sheldon M. Wiederhorn, A Dretzke, J Rodel
The atomic force microscope is used to explore the nature of fracture surfaces in soda lime silicate glass formed near or below the apparent crack growth threshold. Conventional theory suggests that cracks in glass will blunt when subjected to stresses

Network Provisioning as a Game Against Nature

May 1, 2003
Author(s)
Vladimir V. Marbukh
Traditional approaches to network provisioning assume availability of the reliable estimates for the expected demands. This assumption, however, oversimplifies many practical situations when some incomplete information on the expected demands is available
