Strain Rate Dependence of Fracture in a Rubber-Toughened Epoxy System

January 1, 2002
Author(s)
D T. Raghavan, J He, Donald L. Hunston, D Hoffman
The toughening mechanisms in rubber-modified epoxies appear to be viscoelastic in nature since the fracture behavior is dependent on loading rate. This behavior has been studied and modeled only for the most common toughened epoxy system. The present work

Structural Characterization of Porous Low-k SiOC Thin Films Using Novel X-Ray Porosimetry

January 1, 2002
Author(s)
H W. Kim, Wen-Li Wu, Barry J. Bauer, Eric K. Lin, J Y. Kim, Y H. Kim, V. J. Lee
A novel x-ray porosimetry measurement is used to characterize the structure and properties of porous low-k dielectric films after varying process conditions. We determine the film thickness, density depth profile, average density, wall density, and

Superconformal Electrodeposition in Vias

January 1, 2002
Author(s)
Daniel Josell, Daniel Wheeler, Thomas P. Moffat
Conditions for which superconformal filling of vias can be expected are predicted using the curvature enhanced accelerator coverage mechanism to model the effect of accelerator accumulation and area change on local copper deposition rate. Superconformal

Suppression Effectiveness of Aerosols: The Effect of Size and Flame Type

January 1, 2002
Author(s)
J W. Fleming, B A. Williams, R S. Sheinson
This paper summarizes efforts to identify properties of aerosols (liquids and solids) leading to effective fire suppression. It is part of the US Department of Defense’s Next Generation Fire Suppression Technology Program (NGP) supported by the DoD
