X-Ray Absorption Spectroscopy to Probe Interfacial Issues in Photolithography

February 1, 2003
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Daniel A. Fischer, S Sambasivan, Eric K. Lin, Ronald L. Jones, Christopher Soles, Wen-Li Wu, D L. Goldfarb, M Angelopoulos
Control of the shape, critical dimension (CD), and roughness is critical for the fabrication of sub 100 nm features, where the CD and roughness budget are approaching the molecular dimension of the resist polymers1. Here we utilize near edge X-ray

Automated Security Self-Evaluation Tool Technical Documentation, Version 1.03

January 31, 2003
Author(s)
Mark McLarnon, Marianne M. Swanson
The Automated Security Self-Evaluation Tool (ASSET) automates the process of completing a system self-assessment. ASSET will assist organizations in completing the self-assessment questionnaire contained in NIST Special Publication (Special Publication)

Estimating the Work in Integer Partitioning

January 31, 2003
Author(s)
April Andreas, Isabel M. Beichl
For a given set of numbers, the integer partitioning problem is to divide the numbers into two groups, so that the sums of the numbers in each group differ by the smallest amount possible. In a balanced perfect partition, the sums differ by only zero or

Measuring Resin Temperature During Extrusion Using a Fluorescence Technique

January 30, 2003
Author(s)
Anthony J. Bur, S C. Roth, D W. Baugh, K A. Koppi, M A. Spalding, J Gunderson, W C. Buzanowski
We have used a temperature sensitive fluorescent dye, doped into polycarbonate, to monitor the true resin temperature during extrusion processing. The fluorescent dye, perylene, was doped into the polycarbonate at very low concentration. We apply this

NIST CFIT: Testing Disk Imaging Tools

January 27, 2003
Author(s)
James R. Lyle
There is a critical need in the law enforcement community to ensure the reliability of computer forensic tools. A capability is required to ensure that forensic software tools consistently produce accurate and objective test results. The goal of the

Experimental Demonstration of a Technique to Generate Arbitrary Quantum Superposition States of a Harmonically Bound Spin-1/2 Particle

January 24, 2003
Author(s)
A Ben-kish, B M. Demarco, V Meyer, Mary A. Rowe, Joseph W. Britton, Wayne M. Itano, Branislav M. Jelenkovic, Christopher Langer, Dietrich Leibfried, Till P. Rosenband, David J. Wineland
Using a single, harmonically trapped 9Be+ ion, we experimentally demonstrate a technique for generation of arbitrary states of a two-level particle confined by a harmonic potential. Rather than engineering a single Hamiltonian that evolves the system to a

SCUBA-2: a large format submillimeter camera on the James Clerk Maxwell Telescope

January 20, 2003
Author(s)
Wayne Holland, William Duncan, Kent D. Irwin, Anthony Walton, Peter Ade, Ian Robson
SCUBA-2 is a second generation, wide-field submillimeter camera under development for the James Clerk Maxwell Telescope. With over 12,000 pixels, in two arrays, SCUBA-2 will map the submillimeter sky 1000 times faster than the current SCUBA instrument to

Mechanical Behavior of Caulks and Sealants

January 15, 2003
Author(s)
Donald L. Hunston, Christopher C. White
ulks and Sealants are important examples of consumer products where performance depends critically on rheological properties. This work describes the development of a testing and modeling procedure to characterize the basic mechanical properties of such

Time-Division SQUID Multiplexers for Transition-Edge Sensors

January 14, 2003
Author(s)
Kent D. Irwin, James A. Beall, Joern Beyer, Steven Deiker, W.Bertrand (Randy) Doriese, S. L. Ferreira, Gene C. Hilton, Sae Woo Nam, Carl D. Reintsema, Joel Ullom, Leila R. Vale
Microcalorimeters and bolometers based on superconducting transition-edge sensors (TES) are important tools for the detection of photons from millimeter waves through gamma rays, and for applications ranging from materials analysis to astronomy. There is a

Electron Energy Loss Spectroscopy of CeO 2 -x Nanoparticles

January 7, 2003
Author(s)
W Lijun, H J. Wiesmann, A R. Moodenbaugh, Daniel A. Fischer, Y Zhu, M Suenaga
ria has been widely studied due to its applications, such as a catalyst in vehicle emissions system and an electrolyte material in solid oxide fuel cells. Recently, it has been reported that CeO2-x nanoparticles exhibit lattice expansion and valence

A Mechanism for Brightening: Linear Stability Analysis of the Curvature Enhanced Coverage Model

January 6, 2003
Author(s)
Geoffrey B. McFadden, Sam R. Coriell, Thomas P. Moffat, Daniel Josell, Daniel Wheeler, W Schwarzacher
This work presents experiments and theory describing a mechanism for how brighteners in electrolytes function. The mechanism involves change of local coverage of a deposition rate enhancing catalyst adsorbed on the surface through change of local surface

Testing with Model Checker: Insuring Fault Visibility

January 5, 2003
Author(s)
Vadim Okun, Paul E. Black, Yelena Yesha
To detect a fault in software, a test case execution must be chosen so intermediate errors propagate to the output. We describe two modeling methods for specification-based mutation testing using model checkers that guarantee this propagation. We evaluate
