Abstract:	Thin TiN films have many important applications in Integrated Circuit (IC) technology. In spite of its chemical inertness, it is reported that TiN can be oxidized when exposed to oxidants (O2, H2O, etc.). To avoid an undesired oxidation of the metal-nitride layers, a study on this process is necessary. In this work, we present our study on thermal atomic layer deposition (ALD) of TiN films followed by their dry oxidation in oxygen ambient. For both processes, in-situ monitoring by spectroscopic ellipsometry is carried out.
