Surface layer evolution in glow discharge optical emission spectroscopy.
Glow discharge optical emission spectroscopy (GDOES) is a modem analytical technique for the analysis of the chemical composition of bulk materials and the depth profiling of multi-layer structures. Most research in the use of GDOES has concentrated on developing accurate methodologies for …

Synthesis and characterization of atmospheric pressure chemically vapor deposited aluminum
… as 1.2 um/min were achieved. X-ray photoelectron spectroscopy, auger electron spectroscopy, glow discharge optical emission spectroscopy and nuclear reaction analysis revealed that the coatings consisted essentially of pure aluminum (~99 at.%) with oxygen and carbon present as minor constituents. …

Dünne tantalbasierte Diffusionsbarrieren für die Kupfer-Leitbahntechnologie: Thermische Stabilität, Ausfallmechanismen und Einfluss auf die Mikrostruktur des Metallisierungsmaterials
Aufgrund der höheren elektrischen Leitfähigkeit und des größeren Widerstandes gegen Elektromigration im Vergleich zum Aluminium wird seit einigen Jahren Kupfer als Leitbahnmaterial in der Mikroelektronik eingesetzt. Da Kupfer jedoch eine hohe Beweglichkeit in den für die Halbleitertechnologie …
