J R. Lowney, Michael T. Postek, Andras Vladar
A scanning electron microscope (SEM) can be used to measure the dimensions of the microlithographic features of integrated circuits. However, without a good...

A Stewart Platform Lunar Rover

Author(s)
Roger V. Bostelman, James S. Albus, Karl Murphy, T M. Tsai, E Amatucci
A lunar version of the Robocrane is being developed at the Robot Systems Division of the National Institute of Standards and Technology (NIST) to address the...

Flow of Alternative Agents in Piping

Author(s)
Thomas G. Cleary, William L. Grosshandler, Jiann C. Yang
As part of the USAF, Army, Navy and FAA sponsored halon replacement project, the pipe flow characteristics of selected alternative agents for engine nacelle...

Laser Focused Atomic Deposition

Author(s)
Jabez J. McClelland, R E. Scholten, R Gupta, Robert Celotta
We demonstrate the use of a standing-wave laser beam to focus chromium atoms as they deposit onto a silicon surface. A permanent array of Cr lines has been...

Scanning Electron Microscope Metrology

Author(s)
Michael T. Postek
During the manufacturing of present-day integrated circuits, certain measurements must be made of the submicrometer structures composing the device with a high...

Hertzian Contact Resonances

Author(s)
John A. Kramar, T Mcwaid, J Schneir, E C. Teague
The resonant frequency of a sphere in contact with a flat surface was measured as a function of loading force for contacting materials with different elastic...

Microform Calibrations in Surface Metrology

Author(s)
Jun-Feng Song, F Rudder, Theodore V. Vorburger, A Hartman, Brian R. Scace, J Smith
Microform calibrations include the measurement of complex profile forms and position errors of micrometer scale in combination with the measurement of...

Force Calibrations in the Nanonewton Regime

Author(s)
Lowell P. Howard, E C. Teague
An instrument is described which is shown capable of making preliminary measurements of nanonewton forces. A technique is described which allows absolute...
