Surface Effects in Chemically Amplified Photoresists: Environmental Stability and Segregation

February 1, 2004
Author(s)
E Jablonski, Vivek M. Prabhu, S Sambasivan, Daniel A. Fischer, Eric K. Lin, D L. Goldfarb, M Angelopoulos, H Ito
It is well known that chemically amplified photoresists are sensitive to certain airborne molecular contaminants, notably amines, during post exposure delay, although the actual cause and specific failure mechanism are unknown. To assess the effect of low

Surface Enhanced Raman Spectroscopy in a Microfluidic Device

February 1, 2004
Author(s)
D Dunmire, D B. Romero, Guangjun Cheng, Angela R. Hight Walker
Surface enhanced Raman spectroscopy (SERS) is employed to study the solution phase vibrational structure of molecules on gold and silver colloids. Gold and silver colloids show large enhancement factors enabling sub-micromolar detection limits. Using a

Synthesis of Bioconjugated Magnetic Nanoparticles for Magneto-Raman Study

February 1, 2004
Author(s)
Guangjun Cheng, D B. Romero, D Dunmire, Angela R. Hight Walker
We are investigating the effects of an externally applied magnetic field on the structure and magnetic properties of biomolecules (DNA and proteins). A newly constructed, magneto-Raman confocal microscope system couples a cryo-magnet to a triple grating

Techniques for Measurements in Concentrated Systems

February 1, 2004
Author(s)
Vincent A. Hackley
Concentrated suspensions present a number of technical challenges for characterization and monitoring of the solid phase. Recent developments have provided the means to analyze many concentrated systems directly or at solids loadings more closely

Testing: A Key to Building Trust and Confidence in IT Systems

February 1, 2004
Author(s)
S F. Zevin
The ubiquitous computer now touches nearly every aspect of human life. The promise of information technology is improvement to the quality of life. Maintaining trust and confidence in information technology is central to keeping that promise. This is

The Miami2001 Infrared Radiometer Calibration and Intercomparison. Part I: Laboratory Characterization of Blackbody Targets

February 1, 2004
Author(s)
Joseph P. Rice, James J. Butler, B C. Johnson, P J. Minnett, K A. Maillet, T J. Nightingale, S J. Hook, A Abtahi, C J. Donlon, I J. Barton
The second calibration and intercomparison of infrared radiometers (Maiami2001) was held at the University of Miami Rosenstiel School of Marine and Atmospheric Science (RSMAS) during May-June 2001. The participants were from several groups involved with

Towards reproducible SCM Image Interpretation

February 1, 2004
Author(s)
Joseph Kopanski, Jay F. Marchiando, Brian G. Rennex, David S. Simons, R P. Chaudhury
SCM images, and the two-dimensional (2-D) dopant profiles extracted from them, show poor reproducibility from laboratory to laboratory. Major factors contributing to SCM image variability include: poor sample surface and oxide quality, excess carrier

Ultra-Thin gate Oxide Breakdown: A Failure that we can live with?

February 1, 2004
Author(s)
John S. Suehle
As gate oxides are scaled down in thickness in current technologies, the breakdown event caused by TDDB becomes 'softer'. In current technologies where the oxide thickness is less than 2 nm, the breakdown event has become so soft that in some cases circuit

Water Absorption in Thin Photoresist Films

February 1, 2004
Author(s)
B D. Vogt, Christopher L. Soles, Ronald L. Jones, Vivek M. Prabhu, Wen-Li Wu, Eric K. Lin
In this work, we quantify deviations in the moisture absorption into model photoresist films upon changing thickness. Both the thermodynamics and kinetics of the absorption process are examined. Water in the resist films has been shown to have a

XML Schema Development Guidelines. Version 1.0

February 1, 2004
Author(s)
Mark E. Palmer, M Burns, T L. Teague
These guidelines summarize the background, rationale and guiding principles that the FIATECH program is using to produce XML domain schemas for automating information exchanges in the capital facilities industries and over the life cycle of equipment used

Applications of Sinkhorn Balancing: The Monomer-Dimer Problem

January 30, 2004
Author(s)
Isabel M. Beichl, Francis Sullivan
We describe a general Monte Carlo technique based on work of Knuth for estimating the size of trees in backtrack algorithms. This method, based on importance sampling, is used to estimate the number of partial and complete matchings in a bipartite graph

Micromachined Alkali Atom Vapor Cells for Chip-Scale Atomic Clocks

January 30, 2004
Author(s)
Li-Anne Liew, Svenja A. Knappe, John M. Moreland, Hugh Robinson, Leo W. Hollberg, John Kitching
This paper describes the fabrication of chip-sized alkali atom vapor cells, for use in highly miniaturized atomic frequency references, using silicon micromachining and anodic bonding technology. The cells consist of silicon cavities with internal volume

Interoperable Dynamic Tactical Information for Public Safety Officials

January 23, 2004
Author(s)
William D. Davis, D D. Evans
Currently, fire department notification of a building fire comes from either a building fire alarm system monitoring service or a 911 call. The emergency responders know very little about the situation until they arrive on the scene. Information for their

NCWM Publication 15, Interim Meeting Agenda - January 2004

January 21, 2004
Author(s)
Linda D. Crown
This is the agenda for the four Standing Committees of the National Conference on Weights and Measures. The meeting will be held at the Hyatt Regency Bethesda, Bethesda, MD, January 25-28, 2004.

Practical electron-tunneling refrigerator

January 21, 2004
Author(s)
Anna Clark, Anthony Williams, Steve Ruggiero, Marcel L. van den Berg, Joel N. Ullom
We demonstrate a thin-film, solid-state refrigerator based on the removal of hot electrons from a metal by quantum-mechanical tunneling. We have halved the electronic temperature in a macroscopic film from 260 mK to near 130 mK. Both the cooling power and

Progress in the Development of Combustion Databases for Liquid Fuels

January 21, 2004
Author(s)
Wing Tsang
This paper describes the present situation regarding chemical kinetic databases for the simulation of the combustion of liquid fuels. Past work in the area is summarized. Much is known about the, reactions of the smaller fragments from combustion process

Quantitative Characterization of DNA Films by X-ray photoelectron spectroscopy

January 20, 2004
Author(s)
D Y. Petrovykh, H Y. Kimura-Suda, Michael J. Tarlov, L J. Whitman
Self-assembled films of thiolated poly(dT)25 single-stranded DNA (ssDNA) on gold areintroduced as a model system for quantitative characterization of DNA films by XPS. Weevaluate the applicability of a simple substrate-overlayer model for data analysis
