Thermal Expansion Coefficients of Low-K Dielectric Films From Fourier Analysis of X-Ray Reflectivity

July 1, 2000

Author(s)

Charles E. Bouldin, William E. Wallace, G W. Lynn, S C. Roth, Wen-Li Wu

We determine the thermal expansion coefficient of a fluorinated poly (arylene ether) low-k dielectric film using Fourier analysis of x-ray reflectivity data. The approach is similar to that used in Fourier analysis of x-ray absorption fine structure. The

April 1, 2000

Author(s)

Wen-Li Wu, Eric K. Lin, C Jin, J T. Wetzel

A methodology to characterize nanoporous thin films based on a novel combination of high resolution specular x-ray reflectivity and small angle neutron scattering has been advanced to accommodate heterogeneities within the material surrounding nanoscale

Shear Induced Polymer Melt Desorption From an Attractive Substrate

June 24, 1999

Author(s)

Eric K. Lin, R Kolb, Wen-Li Wu, Sushil K. Satija

Shear induced adsorption/desorption of a highly entangled polymer melt from an attractive interface was directly observed using neutron reflectometry. The concentration of poly(methyl methacrylate) (d-PMMA) in a hydrogenated PMMA matrix was measured within

Reduced Polymer Mobility Near the Polymer Solid Interface as Measured by Neutron Reflectivity

June 1, 1999

Author(s)

Eric K. Lin, R Kolb, Sushil K. Satija, Wen-Li Wu

Neutron reflectometry is used to measure the rate of interdiffusion over distances less than 200 between bilayer samples of deuterated and hydrogenated poly(methyl methacrylate) (PMMA) films with the polymer-polymer interface located near the native oxide

Polymer Mobility Near the Polymer/Solid Interface

May 6, 1999

Author(s)

Eric K. Lin, Wen-Li Wu, Sushil K. Satija, R Kolb

Neutron reflectometry is used to measure polymer mobility near an attractive solid surface over distances less than the bulk polymer radius of gyration, R g. Effective diffusion coefficients, D eff, are determined from the rates of interdiffusion between
