Direct Measurement of the Reaction Front in Chemically Amplified Photoresists

July 1, 2002
Author(s)
Eric K. Lin, Sushil K. Satija, Wen-Li Wu, Christopher L. Soles, D L. Goldfarb, B C. Trinque, S D. Burns, Ronald L. Jones, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, M Angelopoulos, C G. Willson
The continuing drive by the semiconductor industry to fabricate smaller structures with photolithography will soon require dimensional control at length scales, (2 to 5) nm, comparable to the size of the polymeric molecules in the materials used to pattern

Document Understanding Conferences Website

Author(s)
Ellen M. Voorhees
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

Dynamic Range Limitations in Phase Doppler Interferometry Measurements

July 1, 2002
Author(s)
J F. Widmann, Cary Presser, Stefan D. Leigh
It has been well established that the dynamic range of phase Doppler interferometry (PDI) size measurements is limited by the photomultiplier tubes (PMT). A statistical method is presented to overcome this limitation by combining data sets collected over

Dynamics in a Two-Level Atom Magneto-Optical Trap

July 1, 2002
Author(s)
X Xu, T Loftus, M J. Smith, John L. Hall, Alan Gallagher, Jun Ye
Alkaline earth metal atoms present an ideal platform for exploring magneto-optic trap (MOT) dynamics, enabling unique and definitive tests of laser cooling and trapping mechanisms. We have measured the trapping beam intensity, detuning, magnetic-field

Fabricating Planar Nanoparticle Assemblies With Number Density Gradients

July 1, 2002
Author(s)
R R. Bhat, Daniel A. Fischer, Jan Genzer
We report on preparing assemblies of gold nanoparticles with continuous gradients in number density on flat silica-covered substrates. The methodology consists of: i) first forming a one dimensional molecular gradient of amino groups (-NH2) on the

Fabrication and Characterization of In-Situ Grown Epitaxial Ba 1-x Sr x Ti0 3 ) Composition Spreads

July 1, 2002
Author(s)
K S. Chang, M A. Aronova, O Famodu, Jason Hattrick-Simpers, S E. Lofland, Ichiro Takeuchi, C J. Lu, Leonid A. Bendersky, H C. Chang
We have used our combinatorial pulsed laser deposition system to in-situ fabricate epitaxial Ba(sub1-x)Sr(sub x)Ti)(sub 3) thin film composition spreads on (100) LaAl0(sub3) substrates. Multimode quantitative microwave microscopy was used to perform

Fire Research: Providing New Tools for Fire Investigation

July 1, 2002
Author(s)
Daniel M. Madrzykowski
Researchers at the National Institute of Standards and Technology's (NIST) Building and Fire Laboratory (BFRL) are working with the U.S. Fire Administration (USFA); the Bureau of Alcohol, Tobacco and Firearms (ATF); and the U.S. Department of Justice to

Fire Safety Research at NIST

July 1, 2002
Author(s)
Anthony P. Hamins
The Fire Research Division is one of four Divisions in the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST). The Division is composed of approximately 58 full time employees, 25 guest scientists and

First Results From the Updated NIST/DARPA EUV Reflectometry Facility

July 1, 2002
Author(s)
S Grantham, Charles Tarrio, M B. Squires, Thomas B. Lucatorto
Currently the most demanding application of extreme-ultraviolet (EUV) optics is in lithography. A commercial extreme-ultraviolet stepper will likely have six or more normal-incidence reflective optics, and the largest of these will be tens of cm in

Formation of InAs/GaAs quantum dots by dewetting during cooling

July 1, 2002
Author(s)
Richard P. Mirin, Alexana Roshko, M. van der Puijl, Andrew G. Norman
We describe a method to form InAs quantum dots on GaAs by cooling an InAs film that is deposited at high substrate temperatures. The reflection high-energy electron diffraction pattern taken after deposition of 1.9 monolayers of InAs on (100) GaAs at 540

Frequency-Domain Measurement of the Photodegradation Process of Fluorescein

July 1, 2002
Author(s)
Adolfas K. Gaigalas, Lili Wang, R F. Vogt
The frequency domain technique is applied to measure the photodegrdation rate offluorescein in aqueous solutions. The illuminating light is modulated and the changes in fluorescence from the illuminated region are detected synchronously. A constant flow

Global Response Modification Factors vs. Member Ductility-Based Modifiers

July 1, 2002
Author(s)
S K. Kunnath, Hai S. Lew, D Friis
Most building structures today are designed using the response modification factors (R-factors) given in the code for different types of structural systems. This paper examines whether ductility-based modifiers for structural members (m-factors)

Histopathologic Reaction of a Calcium Phosphate Cement for Alveolar Ridge Augmentation

July 1, 2002
Author(s)
A Sugawara, K Fujikawa, S K. Kusama, M Nishiyama, S Murai, Shozo Takagi, Laurence Chow
The objective of the present study was to evaluate the feasibility of using a calcium phosphate cement (CPC) in the reconstruction of a defective alveolar ridge in conjunction with implant placement. The CPC consisted of an equimolar amount of tetracalcium
