Combinatorial Study of Ni-Ti-Pt Ternary Metal Gate Electrodes on HfO 2 for the Advanced Gate Stack

October 2, 2006
Author(s)
Kao-Shuo Chang, Martin L. Green, John S. Suehle, Eric M. Vogel, Hao Xiong, Jason Hattrick-Simpers, Ichiro Takeuchi, O Famodu, K Ohnaka, T Chikyow, Prashant Majhi, B H. Lee, M Gardner
We have fabricated combinatorial Ni-Ti-Pt ternary metal gate thin film libraries on HfO2 using magnetron co-sputtering, to investigate flat-band voltage shift (DVfb) and leakage current density (JL) variations. Wavelength dispersive spectroscopy (WDS)

Role of Core Support Material in Veneer Failure of Brittle Layer Structures

September 26, 2006
Author(s)
Ilja Hermann, Sanjit Bhowmick, Brian R. Lawn
A study is made of veneer failure by cracking in all-ceramic crown-like layer structures. Model trilayers consisting of a 1 mm thick external glass layer (veneer) joined to a 0.5 mm thick inner stiff and hard ceramic support layer (core) by epoxy bonding

Self-Assembled Monolayers: Effect of Chain Length on Nanofriction

September 6, 2006
Author(s)
S Hsieh, S Sambasivan, J V. Sengers, Stephen M. Hsu
We measured the interfacial friction of a series of alkylsilanes with chain lengths from C5 to C30 on silicon (100) surfaces using an Atomic Force Microscope (AFM). The dependence of the friction on chain length exhibits an optimum curvature with C12
