Annealing a titanium-rich carbide film deposited on silicon produces, in a single processing step, both a stable titanium silicide contact and a titanium carbide diffusion barrier between the silicide and a subsequently formed overlying layer of aluminum. Reliable low-resistance contacts to VLSI devices are thereby provided in a cost-effective fabrication sequence. Other metallization systems, comprising a silicide and a diffusion barrier to aluminum formed in a single processing step, are also described. |
