The reaction mixture is stored in a high-pressure sealed container and synthesised by growing ultra-thin "nanowires" of tungsten oxide on the surface of tiny particles of tantalum nitride
Until now this has only been possible using expensive military-grade tantalum nitride
Built using a moisture-resistant tantalum nitride
resistive film technology, the new E/H ([Ta.sub.2]N) resistors offer enhanced specifications for military and aerospace applications, including tolerances to 0.1 percent and TCR of 25 ppm/[degrees]C.
"The big breakthrough for us in developing ceramic sensors was demonstrating a fine-lined thin-film tantalum nitride
rosette strain gauge using patterning technology originally developed for platinum thin films.
, tantalum silicide and ruthenium oxide are common resistor materials, although the materials may be changed to suit the resistivity and power handling requirements, temperature coefficient of resistance (TCR), and processing capabilities.
Designated the WBC Series, the resistors feature self-passivating tantalum nitride
thin-film technology on silicon substrates.
This is facilitated by a layer of resistive metallization of either nichrome or tantalum nitride
in a predetermined sheet resistivity and etched or laser trimmed to the value and tolerance required by the design.
Using breakthrough ALD technology, the iCuB/S system provides the key to future copper nano-chips by enabling an ultrathin, conformal tantalum nitride
(TaN) barrier layer that is compatible with advanced low (kappa) dielectric films.
Designated the WBC Series, the resistors feature the company's self-passivating tantalum nitride
thin film technology on silicon substrates for desirable stability over time and temperature.
is a great barrier layer but does not stick to much except to titanium.
