ABSTRACT:
Integrated circuits employing titanium nitride are significantly improved by using a specific method for formation of the titanium nitride in the device fabrication. In particular, a plasma such as one formed in an electron cyclotron resonance apparatus is employed to dissociate a source of nitrogen and a source of hydrogen and the dissociation products are combined at the integrated circuit deposition substrate with titanium tetrachloride. The resulting deposition is essentially devoid of chlorine and has advantageous step-coverage properties.
