Laser Trackers: Testing and Standards

January 1, 2007
Author(s)
Steven D. Phillips
Laser trackers are now the tool of choice for large scale coordinate metrology. They are transportable allowing reconfigurable production facilities at a lower capital cost than large CMMs. Trackers now include absolute distance measuring (ADM) capability

Linewidth Measurement Based on Automatically Matched and Stitched Images

January 1, 2007
Author(s)
Wei Chu, Joseph Fu, Ronald G. Dixson, Theodore V. Vorburger
The emergence of ultra-sharp carbon nanotube (CNT) tips provides a new approach to minimize the distortion of the measured linewidth profile caused by interaction with the fmite probe tip size. However, the inevitable tilt angle resulting from attaching

NIST Standard Bullets and Casings Project

Author(s)
Jun-Feng Song, Theodore V. Vorburger, Susan M. Ballou, Thomas Brian Renegar, Li Ma, Eric P. Whitenton, David R. Kelley, Robert A. Clary, A Zheng, M Ols
The National INstitute of Standards and Technology (NIST) standard bullets and casings project will provide support to firearm examiners and to the National Integrated Ballistics Information Network (NIBIN) in the United States. The standard bullet is

Roundness Measurements Using the NIST Fiber Probe

January 1, 2007
Author(s)
Balasubramanian Muralikrishnan, Jack A. Stone Jr., John R. Stoup
We have described a fiber probe for dimensional measurement of micro-holes in the 2004 and 2006 ASPE annual meetings. In this abstract, we describe the adaptation of this probe for measuring roundness of tiny holes and knife edge apertures. In its current

Surface Metrology Algorithm Testing System

January 1, 2007
Author(s)
Son H. Bui, Theodore V. Vorburger
This paper presents the development of a Web-based surface metrology algorithm testing system. The system includes surface analysis tools and a surface texture specimen database for parameter evaluation and algorithm verification. The system runs from a

Reenie M. Parris
The United States Pharmacopeia (USP) is a private standards-setting body created in 1820 by practitioners who wished to promote the quality of therapeutic products in commerce. The principal product of USP, then and now, is the United States Pharmacopeia

Evaluation Specimens for Izod Impact Machines (SRM 2115): Report of Analysis

October 1, 2006
Author(s)
Thomas A. Siewert, Jolene Splett, Raymond Santoyo
In the past few years, we have received a number of requests for verification specimens for Izod impact machines, similar to what we offer for Charpy impact machines. Although there are similarities between Izod and Charpy impact testing, there are some

Parametric Uncertainty in Optical Image Modeling

September 18, 2006
Author(s)
James E. Potzick, Egon Marx, M P. Davidson
Optical photomask feature metrology and wafer exposure process simulation both rely on optical image modeling for accurate results. While it is fair to question the accuracies of the available models, model results also depend on several input parameters

Illumination Optimization for Optical Semiconductor Metrology

September 1, 2006
Author(s)
Bryan M. Barnes, L Howard, Richard M. Silver
Uniform sample illumination via K hler illumination, is achieved by establishing a pair of conjugate focal planes; a light source is focused onto the condenser lens aperture while the image of the field aperture is focused at the plane of the specimen

Standards for Plasma and Serum Protoemics in Early Cancer Detection: A Needs Assessment Report From the NIST-NCI SMART Workshop, August 18-19, 2005

September 1, 2006
Author(s)
Peter E. Barker, Paul D. Wagner, Stephen E. Stein, David M. Bunk, S Srivastava, Gilbert Omenn
The National Institute of Standards and Technology (NIST) and the National Cancer Institute (NCI) co-sponsored a workshop on August 18-19, 2005 to examine needs for reference materials to support biomarker discovery for early cancer detection. Needs for
