The Boundary of X-Ray and Electron Tomography

January 3, 2005
Author(s)
Zachary H. Levine
Samples a few micrometers in total size offer a challenge to both x-ray and electron tomography. X-ray tomography originated imaging the human body with millimeter resolution, but the resolution has been reduced by over 7 orders of magnitude by the use of

Imaging Material Components of an Integrated Circuit Interconnect

January 1, 2004
Author(s)
Zachary H. Levine, Steven E. Grantham, D J. Paterson, I McNulty, I C. Noyan, T M. Levin
Two regions of interest on a copper/tungsten integrated circuit interconnect were imaged using two techniques: (a) the absorption spectrum was measured at 15 x-ray energies between 1687 eV and 1897 eV; and (b) the x-ray fluorescence spectrum was recorded

Mass Absorption Coefficient of Tungsten and Tantalum, 1450 eV to 2350 eV: Experiment, Theory, and Application

January 1, 2003
Author(s)
Zachary H. Levine, S Grantham, Charles S. Tarrio, D Paterson, I McNulty, T M. Levin, A L. Ankudinov, J J. Rehr
The mass absorption coefficient of tungsten and tantalum was measured with soft x-ray photons from 1450 eV to 2350 eV using an undulator source. This includes the M 3, M 4, and M 5 absorption edges. X-ray absorption fine structure was calculated within a

Web page for the Computational Material Science Network(administered at U. Washington) based on the following WERB-approvedmanuscripts:Z.~H.~Levine, S.~Grantham, C.~Tarrio,D.~J.~Paterson, I.~McNulty, T.~M.~Levin,A.~L.~Ankudinov, and J.~J.~Rehr,``Mass

Diffractive Optics From Self-Assembled DNA

August 1, 2002
Author(s)
Zachary H. Levine
An algorithm is presented for assembling tiles into a variable spaced grating, the one-dimensional analogue of Fresnel zone plate. The algorithm supports blazing. The x-ray properties of such a grating, assumed to be constructed form DNA are estimated

The Trouble with Calcium Floride

March 1, 2002
Author(s)
John H. Burnett, Zachary H. Levine, Eric L. Shirley
We discuss the intrinsic birefringence of calcium fluoride and othercrystalline materials that may be used in the optics for 193nm and 157nmlithography, including the characterization of the effect and itsimplications for performance of lens systems at

Mass Absorption Coefficient of Tungsten for 1600-2100 eV

February 1, 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
