The Programs of the Manufacturing Engineering Laboratory 2005

April 8, 2005
Author(s)
Lisa J. Fronczek, Bessmarie A. Young
The National Institute of Standards and Technology s Manufacturing Engineering Laboratory (MEL) strengthens the U.S. economy and improves the quality of life by working with the U.S. manufacturing industry to develop and apply infrastructural technology

Improvement in the Low Energy Collection Efficiency of Si(Li) X-Ray Detectors

April 7, 2005
Author(s)
C E. Cox, Daniel A. Fischer, W G. Schwarz, Y Song
Soft X-ray beam-line applications are of fundamental importance to material research, and commonly employ high-resolution Si(Li) detectors for Energy Dispersive Spectroscopy. However, the measurement of X-rays below 1 keV compromised by absorption in the

Photomask Feature Metrology

April 7, 2005
Author(s)
James E. Potzick
This chapter discusses some general issues with regard to measurement of the size and placement of the features on a photomask.
Since all linewidth and placement measurements derive from the location of a feature's edges, the Chapter starts with a

Reaction gas chromatography/mass spectrometry. 2the use of catalytic on-line dehydrogenation for the investigation of alcohols by gas chromatography/mass spectrometry

April 7, 2005
Author(s)
Anzor I. Mikaia, Vladimir Smetanin, Vladimir G. Zaikin, Alla V. Antonova, Nikolay A. Prostakov
A GC-MS method is developed for structure determination of aliphatic within mixtures. It involves online application of a gas-phase dehydrogenation reaction after GC separation and before MS analysis. Primary and secondary alcohols are converted into

Elastic-property measurements of ultrathin films using atomic force acoustic microscopy

April 5, 2005
Author(s)
Malgorzata Kopycinska-Mueller, Roy H. Geiss, Jens Mueller, Donna C. Hurley
Atomic force acoustic microscopy (AFAM), an emerging technique that affords nanoscale lateral and depth resolution, was employed to measure the elastic properties of ultrathin films. In this study we measured the indentation modulus M of three nickel films

Microfabricated atomic frequency references

April 5, 2005
Author(s)
John Kitching, Svenja A. Knappe, Li-Anne Liew, John Moreland, Hugh Robinson, P Schwindt, V Shah, Leo W. Hollberg
We describe a design for a microfabricated atomic frequency reference with a volume of several cubic millimetres and a power dissipation in the range ot tens of milliwatts. It is anticipated that this frequency reference will be capable of achieving a

Autonomy Levels for Unmanned Systems (ALFUS) Framework: An Update

April 4, 2005
Author(s)
Hui-Min Huang, K Pavek, James S. Albus, Elena R. Messina
The initial construct of the framework for the Autonomy Levels of Unmanned Systems (ALFUS) was presented in the 2004 SPIE Defense and Security Symposium. This paper describes the continuing development effort and further accomplishments made by the Ad Hoc

Comparison of SEM and HRTEM CD-Measurements Extracted From Monocrystalline Tes-Structures Having Feature Linewidths From 40 nm to 240 nm

April 4, 2005
Author(s)
W Tan, Robert Allen, Michael W. Cresswell, Christine E. Murabito, B C. Park, Ronald G. Dixson, William F. Guthrie
CD measurements have been extracted from SEM and HRTEM images of the same set of monocrystalline silicon features having linewidths between 40 and 200 nm. The silicon features are incorporated into a new test structure which has been designed to facilitate

Flammability of Polymer Clay Nanocomposites Consortium:Final Report

April 4, 2005
Author(s)
Jeffrey W. Gilman, Takashi Kashiwagi, A B. Morgan, Rick D. Davis, Richard H. Harris Jr., L D. Brassell
In 1997 NIST reported that polymer layered-silicate (clay) nanocomposites exhibit reduced flammability, in the form of reduced heat release rate (HRR). The unique character of this new approach to flame retard polymeric materials was the dual benefit of

Metrology for High-Voltage, High-Speed Silicon-Carbide Power Devices

April 4, 2005
Author(s)
Allen R. Hefner Jr., David W. Berning, Colleen E. Hood
Performance metrics and test instrumentation needs for emerging high-voltage, high-speed SiC power devices are described. Unique power device and package thermal measurement test systems and parameter extraction methods are introduced, and applied to

Out-of-Plane Polarimetric Imaging of Skin: Surface and Subsurface Effects

April 4, 2005
Author(s)
J C. Ramella-Roman, D Duncan, Thomas A. Germer
True borders of certain skin cancers are hard to detect by the human eye. For this reason, techniques such as polarized light imaging have been used to enhance skin cancer contrast before Mohs surgery procedures. In standard polarized light imaging the

An Overview and Analysis of PDA Forensic Tools

April 2, 2005
Author(s)
Wayne Jansen, Richard Ayers
Mobile handheld devices are becoming evermore affordable and commonplace in society. When they are involved in a security incident or crime, forensic specialists require tools that allow proper extraction and speedy examination of any digital evidence

Standards for Validation of Cancer Biomarkers

April 2, 2005
Author(s)
Catherine D. O'Connell, Donald H. Atha, J P. Jakupciak
Over the past 10 years, DNA testing to identify disease associated mutations and specific organisms, which represent public health and safety concerns, have become major targets for laboratory testing. RNA testing is also emerging for gene expression, both

2-D Imaging of Temperature in CF 4 Plasmas

April 1, 2005
Author(s)
Kristen L. Steffens, Mark A. Sobolewski
Two-dimensional maps of rotational temperature were determined in CF4 plasmas using planar laser-induced fluorescence of CF. Experiments were performed in a capacitively-coupled, parallel plate plasma reactor at pressures from 200mTorr (26.7Pa) to 800mTorr

A Model Driven Standards Process

April 1, 2005
Author(s)
Arthur Griesser
Explains how and why UML models fit into a robust formal standardization process based on the best practices of software development.

A Simple Transfer-Optics System for an Extreme-Ultraviolet Synchrotron Beamline

April 1, 2005
Author(s)
Charles S. Tarrio, Steven E. Grantham, Robert E. Vest, K Liu
Beamlines at synchrotron radiation facilities often have interchangeable endstations to allow several different experiments to use the output of a single monochromator. However, for endstations that are sufficiently large, this is not possible. We have

An Architecture for Semantic Enterprise Application Integration Standards

April 1, 2005
