Process Representation Using Architectural Forms: Accentuating the Positive

December 1, 1999
Author(s)
Joshua Lubell, Craig I. Schlenoff
The PSL (Process Specification Language) project is creating a standard language for process specification to serve as an interlingua to integrate multiple process-related applications throughout the manufacturing life cycle. This interchange language is

Refractivity of Nitrogen Gas in the Vacuum Ultraviolet

December 1, 1999
Author(s)
Ulf Griesmann, John H. Burnett
We have measured the refractivity of nitrogen gas in the ultraviolet and vacuum ultraviolet using a Fourier transform spectrometer. A new two-term Sellmeier formula for the standard refractivity between 145 nm and 270 nm is derived.

S and Si Ion-Implantation in GaSb Grown on GaAs

December 1, 1999
Author(s)
M V. Rao, A K. Berry, T Q. Do, M C. Ridgway, P Chi, J Waterman
Single and multiple energy S and Si ion-implantations were performed at room temperature (RT) and at 200 C into GaSb epitaxial layers grown on semi-insulating GaAs substrates. The implanted material was annealed with a Si 3N 4 cap at 400-600 C for 5 min

Scotch Pine Christmas Tree Fire Tests. REPORT OF TEST FR 4010

December 1, 1999
Author(s)
D W. Stroup, Laurean A. DeLauter, Jack C. Lee, G Roadarmel
A series of fire tests were conducted to characterize the potential hazard from ignition of Scotch Pine Christmas trees. Heat release rate was measured as a function of time from ignition using a large calorimeter. In addition, radiative flux and total

Size Change of Dendrimers in Concentrated Solution

December 1, 1999
Author(s)
A Topp, Barry J. Bauer, T J. Prosa, R L. Scherrenberg, Eric J. Amis
Solutions of the poly(propylene imine) dendrimers DAB-dendr-(NH 2) 23 and DAB-dendr-(NH 2) 64 in methanol are investigated with small angle neutron scattering over the range of dendrimer mass fraction 0.01# x # 0.80. The single particle scattering function
