In advanced silicon technology, tungsten Titanium (W/Ti) alloy films are frequently used as diffusion barriers and etch-stop layers in combination with aluminium-based interconnections.The barrier films have been characterized with the help of cross-sectional transmission electron microscopy, electron diffraction, electrical resistivity probing, Rutherford back-scattering spectrometry and X-ray diffraction.
