Furnace annealing effects in the formation of titanium ...

Titanium silicide formation takes place by mean of the diffusion of the silicon atoms across the Ti/Si interface, activated by the annealing process. Depending on the annealing process temperature, the gases introduced in the annealing chamber form some agglomerates on the top of the Ti layer with different chemical and physical composition.

Raman Scattering Characterization of Titanium Silicide ...

Different titanium-silicide and titanium-oxide spectral signatures are observed which can be used to characterize the thin-film reactions. In addition, the Raman spectrum of metallic Ti deposited on Si is detected and is used to monitor the Si interdiffusion. The 40 nm thick Ti films were evaporated in UHV or high-vacuum environments, and in ...

Agglomeration in Titanium Silicide Films

2020-9-11 · Figure 146b shows the schematic illustration of the surface and interfacial energies of the TiSi 2 /Si system. Morphological degradation of TiSi 2 often referred to as agglomeration occurs as the TiSi 2 /Si system attempts to lower the overall energy of the system. If sufficient thermal energy is provided, silicon atoms diffuse through the silicide film and epitaxially precipitates out at ...

Versatile Titanium Silicide Monolayers with Prominent ...

2019-5-25 · On the basis of global structure search and density functional theory calculations, we predict a new class of two-dimensional (2D) materials, titanium silicide (Ti2Si, TiSi2, and TiSi4) monolayers. They are proved to be energetically, dynamically, and thermally stable and own excellent mechanical properties. Among them, Ti2Si is a ferromagnetic metal with a magnetic moment of 1.37 μB/cell ...

Grain boundary diffusion and growth of titanium …

A kinetics study of titanium silicide formation is described. The results show that a fine grained precursor layer exist in between the well developed C-54 silicide layer and the unreacted titanium film. This layer is a mixture of C49-TiSiV2 and unreacted titanium. The fact that no C54-TiSi2 formed directly from the Ti-Si reaction suggests that the nucleation of C49-TiSi2 is easier than that ...

Titanium salicide process flow - Plasma Etching - …

2020-12-18 · Titanium is annealed in nitrogen. The surface of titanium will react with nitrogen to form TiN, and this TiN film will suppress lateral growth of the salicide over the spacers. A simple one-step anneal in argon, which would produce a predictable thickness of titanium silicide, is not possible because of excessive lateral growth over the spacers.
