31. Iridium Barriers for Direct Copper Electrodeposition in Damascene Processing.
Published: 10/1/2006
Authors: Daniel Josell, John E Bonevich, Thomas P Moffat

32. Underpotential Co-Deposition of Cu_subscript(1-x)Pt_subscript(x) Alloys
Published: 9/30/2006
Authors: J Mallett, Ugo Bertocci, Erik B. Svedberg, John E Bonevich, Alexander J. Shapiro, William F. Egelhoff Jr., Thomas P Moffat
Abstract: The electrodeposition of Cu_subscript (1-x)Pt_subscript(x) alloys by underpotential co-deposition of Cu with Pt is demonstrated using an H_subscript(2)SO_subscript(4)-CuSO_subscript(4-)PtCl_subscript(4)_superscript(2-) electrolyte. The composition a ...

33. Electrodeposition of Cu on Ru Barrier Layers for Damascene Processing
Published: 12/2/2005
Authors: Thomas P Moffat, Marlon L Walker, P J Chen, John E Bonevich, William F. Egelhoff Jr., Lee J Richter, Daniel Josell, C A Witt, T Aaltonen, M Ritala, M Leskela
Abstract: Superfilling of sub-micrometer trenches by direct copper electrodeposition onto PVD and ALD Ru barriers is demonstrated. The Cu nucleation and growth mode is found to be sensitive to the oxidation state of the Ru surface as well as the copper deposi ...

34. Fabrication and Measurement of Tall Stacked Arrays of SNS Josephson Junctions
Published: 6/1/2005
Authors: Nicolas Hadacek, Paul David Dresselhaus, Yonuk Chong, Samuel Paul Benz, John E Bonevich
Abstract: We have made tall, uniform stacked Josephson junction arrays by developing an etch process using an inductively coupled plasma etcher. This process produces vertical profiles in thin-film multilayers of alternating superconducting and normal metals. ...

35. Interparticle Interaction Effects in the Magnetic Properities NiO Nanorods
Published: 5/1/2005
Authors: M Seehra, H Shim, P Dutta, A Manivannan, John E Bonevich
Abstract: Magnetic properties of sol-gel synthesized 5 nm nanorods of NiO, with and without oleic acid coating to affect interparticle interactions, are reported. Particle morphologies were studied by transmission electron microscopy and temperature variations ...

36. Origin of Exchange Decoupling Effects in High-Coercivity Air-Annealed CoPd Multilayers
Published: 5/1/2005
Authors: William F. Egelhoff Jr., Robert D McMichael, J Mallett, Alexander J. Shapiro, Cedric John Powell, John E Bonevich, J H Judy, J H Thomas, Erik B. Svedberg
Abstract: We have achieved excellent exchange decoupling of grains in CoPd multilayers by annealing in air at 300 C. Samples exhibit a slope in the hysteresis loop close to 1.0, nucleation fields as large as 1.1 T, and coercivities as large as 1.6 T. These are ...

37. X-Ray Diffraction Characterisation of Nanoparticle Size and Shape Distributions: Application to Bimodal Distributions
Published: 9/30/2004
Authors: N G Armstrong, W Kalceff, James P Cline, John E Bonevich, P A Lynch, C C Tang, S P Thompson

38. A Bayesian/Maximum Entropy Method for the Certification of a Nanocrystallite-Size NIST Standard Reference Material
Published: 7/1/2004
Authors: N G Armstrong, W Kalceff, James P Cline, John E Bonevich
Abstract: A Bayesian/Maximum Entropy (MaxEnt) method for determining crystallite size distribution and morphology from size-broadened x-ray line profiles is presented. This method will be used in certifying a nanocrystallite-size standard reference material ( ...

39. Electrical Properties of Superfilled Sub-Micrometer Silver Metallizations
Published: 7/1/2004
Authors: Daniel Josell, C + Burkhard, David R Kelley, Yi-Wen Cheng, R R Keller, John E Bonevich, Y Li, B C Baker, C A Witt, Thomas P Moffat

40. Bayesian Inference of Nanoparticle-Broadened X-Ray Line Profiles
Series: Journal of Research (NIST JRES)
Published: 2/1/2004
Authors: N G Armstrong, W Kalceff, James P Cline, John E Bonevich
Abstract: A single and self-contained method for determining the crystallite-size distribution and shape from experimental line profile data is presented. We have shown that the crystallite-size distribution can be determined without assuming a functional for ...
