Abstract: This article reports on a new class of amorphous a-Si3N4/MeNx nanocomposite coatings with a high (≥50 vol.%) content of Si3N4 phase; here Me=Zr, Ta, Mo and W. These nanocomposites exhibit high (>1000°C) thermal stability against crystallization and high (>1000 °C) oxidation resistance if the metal Me incorporated in the nanocomposite is correctly selected. It was found that the Zr-Si-N film deposited on Si(100) substrate exhibits no increase of the mass (m=0) in thermogravimetric measurements performed in flowing air up to 1300 °C, i.e. up to the temperature that is the thermal limit for Si substrate but not for nanocomposite.

Abstract: The paper analysis the effect of energy E, delivered to the growing film by bombarding ions and fast condensing atoms, on its (i) structure, (ii) elemental and phase composition and (iii) physical properties. A special attention is devoted to the macrostress s generated in sputtered films under ion bombardment. The conditions under which thick, low-stress sputtered films can be produced are given.
