A Combinatorial Methodology to Discovering the Material Factors Controlling Resist Line Edge Roughness, Shape, and Critical Dimension

January 28, 2002
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Ronald L. Jones, Eric K. Lin, Christopher Soles, Wen-Li Wu, D M. Goldfarb, M Angelopoulos
A combinatorial research methodology is discussed to determine the material factors that control line edge roughness (LER), shape, and critical dimension (CD) of developed photo-resist features. The approach involves generating a gradient of processing

Determination of Active Site Residues in Escherichia Coli Endonuclease VIII

January 25, 2002
Author(s)
S. M. Burgess, Pawel Jaruga, M L. Dodson, Miral M. Dizdar, R S. Lloyd
Endonuclease VIII from Escherichia coli is a DNA glycosylase/lyase that removes oxidatively damaged bases. EndoVIII is a functional homologue of endonuclease III, but a sequence homologue of formamidopyrimidine DNA glycosylase (Fpg). Using multiple

Using Sensor Signals to Analyze Fires

January 25, 2002
Author(s)
William D. Davis
An algorithm is developed that predicts the concentration of smoke and gases such as carbon monoxide in the ceiling jet produced by an axisymmetric fire. A sensor-driven fire model is described and is used to predict the fire hazards in a two-level

Mass Absorption Coefficient of Tungsten, 1600 eV to 2100 eV

January 24, 2002
Author(s)
Zachary H. Levine, S Grantham, I McNulty
The transmission of soft x-rays with photon energies from 1606 eV to 2106 eV was measured for tungsten using thin film samples and a synchrotron source. This region includes the M IV and M V edges. The two tungsten films had thicknesses of 107.7 10 nm and

Superconformal Deposition by Surfactant-Catalyzed Chemical Vapor Deposition

January 24, 2002
Author(s)
Daniel Josell, Daniel Wheeler, Thomas P. Moffat
The curvature enhanced accelerator coverage (CEAC) mechanism recently proposed to explain superconformal filling of fine trenches during copper electrodeposition is shown to also explain superconformal filling and roughness evolution during iodine

Using Sensor Signals to Analyze Fires

January 23, 2002
Author(s)
William D. Davis, Thomas G. Cleary, Michelle K. Donnelly, S. D. Hellerman
Building fire sensors are capable of supplying substantially more information to the fire service than just the simple detection of a possible fire. Nelson, in 1984, recognized the importance of tying all the building sensors to a smart fire panel. In

Effective Hamiltonian Study of PZT 95/5

January 21, 2002
Author(s)
K Leung, Eric J. Cockayne, A F. Wright
An effective Hamiltonian is constructed for PbZr0.95Ti0.05O3. It is parameterized using ab initio results computed in the virtual crystal approximation. The phase diagram depends sensitively on the energetic competition between the stable orthorhombic

Thermal Longevity of Nano-Multilayer Magnetic Media

January 21, 2002
Author(s)
Edward Della Torre, Lawrence H. Bennett
A common concern about the use of particles a few nanometers in size in their stability. This paper addresses a technique for estimating the longevity on the basis of measurements that can be made in a reasonable time. Using the recently developed Preisach

Capacitive Probe Microscopy

January 15, 2002
Author(s)
Joseph J. Kopanski
A scanning capacitance microscope (SCM) combines a differential capacitance measurement with an atomic force microscope (AFM). The AFM controls the position and contact force of a scanning probe tip, and a sensor simultaneously measures the capacitance

The New Homeland Security: Challenges for a Great Nation

January 9, 2002
Author(s)
Ronald S. Ross
This article reiterates the importance of homeland security in light of the events of September 11th and the necessity to integrate information technology security into enterprise security. Now, more than ever, the challenges of homeland security require a

Chapter 19 Shock and Vibration Standards

January 4, 2002
Author(s)
David J. Evans, Henry C. Pusey
Chapter 19 is concerned with shock and vibration standards covering: terminology; use and calibration of transducers and instrumentation; shock and vibration generators; structures and structural systems; vehicles including land-based, airborne, and ocean

Prototype Software for Contaminant-Based Design

January 2, 2002
Author(s)
George Walton, Andrew K. Persily
Outdoor air intake rates of mechanical ventilation systems have traditionally been determined using prescriptive methods based on ventilation requirements per unit floor area or per occupant. This approach has serious shortcomings. It provides no

2002 Weights and Measures Directory

January 1, 2002
Author(s)
L T. Sebring
This directory is a listing of weights and measures officials in the U.S. and its territories. It includes the official's agency, title, address, phone, fax, e-mail, and some url addresses.

A 100 GHz AM and PM Noise Measurement System: Preliminary Design and Performance

January 1, 2002
Author(s)
David A. Howe, Craig W. Nelson, F L. Walls, J F. Garcia nava, Archita Hati, A Sen Gupta
A 1OO GHz AM and PM noise measurement system is described. The basic approach to its construction is to apply existing state-of-the-art, cross-correlation noise measurement techniques to 1OO GHz (W-band).
