Water Distribution Within Immersed Polymer Films

February 1, 2005
Author(s)
B D. Vogt, Christopher Soles, Vivek Prabhu, Sushil K. Satija, Eric K. Lin, Wen-Li Wu
The emergence of immersion lithography as a potential alternative for the extension of current lithography tools will require a fundamental understanding of the interactions between the photoresist and the immersion liquid such as water. The water

Water Immersion of Model Photoresists: Interfacial Influences on Water Concentration and Surface Morphology

February 1, 2005
Author(s)
B D. Vogt, D L. Goldfarb, M Angelopoulos, Christopher Soles, C M. Wang, Vivek Prabhu, P M. McGuiggan, Jack F. Douglas, Eric K. Lin, Wen-Li Wu, Sushil K. Satija
Immersion lithography has emerged as an alternative to the 157 nm node and as such understanding of the interactions between the photoresist and immersion fluid (water) has become a pressing issue. The water concentration within the model photoresist films

A Numerical Method for Mass Spectral Data Analysis

January 31, 2005
Author(s)
Anthony J. Kearsley, William E. Wallace, Javier Bernal, Charles M. Guttman
The new generation of mass spectrometers produces an astonishing amount of high-quality data in a brief period of time leading to inevitable data analysis bottlenecks. Automated data analysis algorithms are required for rapid and repeatable processing of

Camera Calibration for a Manufacturing Inspection Workstation

January 31, 2005
Author(s)
Tsung-Ming Tsai
A CCD camera mounted on a manufacturing part inspection workstation is calibrated for measuring 3D part geometry. It is calibrated by using computer algorithms to analyze data collected from a specially designed calibration image pattern. The calibration

Influence of Tip Wear on Atomic Force Acoustic Microscopy Experiments

January 31, 2005
Author(s)
Malgorzata Kopycinska-Mueller, Roy H. Geiss, Paul Rice, Donna C. Hurley
Tip wear and its corresponding change in geometry is a major impediment for quantifying atomic force acoustic microscopy (AFAM). To better understand the process of tip wear and its influence on AFAM measurements of material elastic properties, we have

Microfabricated Atomic Clocks

January 30, 2005
Author(s)
John E. Kitching, Svenja A. Knappe, Li-Anne Liew, P Schwindt, V Shah, John Moreland, Leo W. Hollberg
We summarize the development of microfabricated atomic frequency references at NIST. The physics packages of these devices have volumes near 10 mm3, power dissipation below 150 mW and can potentially achieve a fractional frequency instability in the range

Maximum Likelihood Estimation for an Observation Driven Model for Poisson Counts

January 28, 2005
Author(s)
Richard D. Davis, William T. Dunsmuir, Sarah B. Streett
This paper is concerned with an observation driven model for time series of counts whose conditional distribution given past observations follows a Poisson distribution. This class of models is capable of modeling a wide range of dependence structures and

Microwave transitions and nonlinear magneto-optical rotation in anti-relaxation-coated cells

January 27, 2005
Author(s)
D Budker, Leo W. Hollberg, Derek F. Kimball, John E. Kitching, S Pustelny, V V. Yashchuk
Using laser optical pumping, widths and frequency shifts are determined for microwave transitions between ground-state hyperfine components of {8s}Rb and d{87}Rb atoms contained in vapor cells with alkane anti-relaxation coatings. The results are compared

Single Molecule Fluorescence Resonance Energy Transfer of a RNA Kissing Complex

January 27, 2005
Author(s)
Peter Yim, Xiaoyi Y. Zhang, E S. DeJong, J M. Carroll, John P. Marino, Lori S. Goldner
We used single molecular fluorescence resonance energy transfer (FRET) to understand the conformation of a RNA loop to loop complex, termed a kissing complex. The kissing complex formed by two Escherichia Coli (ColE1) plasmid-encoded transcripts, RNA I and

Diffraction Effects in Radiometry

January 26, 2005
Author(s)
Eric L. Shirley
This is the draft submitted to be Chapter 10 of the book, Modern Radiometric Practice, edited by Albert C. Parr, Raju U. Datla, and James W. Gardner. This chapter is intended to discussion issues of diffraction effects on radiometric measurements.

Appendix A; Example: Calibration of a Cryogenic Blackbody

January 22, 2005
Author(s)
Raju V. Datla, Eric L. Shirley, Albert C. Parr
This manuscript is intended to be an Appendix in a book on radiometry, The Practice of Optical Radiometry. The Appendix is to provide a real example of a blackbody calibration, in order to demonstrate the statistical analysis of data. The role of

Carbon multi-walled nanotubes grown by HWCVD on a pyroelectric detector

January 21, 2005
Author(s)
John H. Lehman, Rohit Deshpande, Paul Rice, Bobby To, Anne Dillon
Carbon multi-wall nanotubes (MWNTs) were grown on a lithium niobate (LiNbO3) pyroelectric detector with a nickel film as the catalyst by hot-wire chemical vapor deposition (HWCVD). Two detectors are documented, each with slightly different deposition

Rapid heating of a strongly coupled plasma at the solid-liquid phase transition

January 21, 2005
Author(s)
M J. Jensen, T Hasegawa, John Bollinger, Daniel H. Dubin
Between 10 4 and 10u6 A9Be^+ ions were trapped in a Penning trap and laser-cooled to siml K, where they formed a crystalline plasma. We measured the ion temperature as a function of time after turning off the laser-cooling and observed a rapid temperature

Generation of Lattice Wannier Functions via Maximum Localization

January 20, 2005
Author(s)
Eric J. Cockayne
A method is presented for generating approximate lattice Wannier functions (LWF) for lattice dynamics problems, using the dynamical matrix for a supercell as input. The lattice Wannier functions fit selected phonon frequencies and eigenvectors exactly, are

Design, Development and Testing of a Hybrid Device for In-Situ Testing of Sealant

January 19, 2005
Author(s)
Christopher C. White, E Embree, C Buch
A new hybrid in-situ sealant-testing device that uses movement to both characterize and fatigue standard ASTM C719 sealant samples is described. This five sample device, records the force-response data for every deformation cycle of every sample. From this
